If you're a Chinese CS/AI master's student in the US, your job search has two parallel tracks: stay in the US on OPT/H1B, or return to China for campus recruiting. Most students only figure out which track to run — and what to do this week — in February or March, when the best offers on both sides are already gone. This guide, written from the perspective of an engineer who sits on real hiring loops, lays out the full 2026-27 calendar, the visa pitfalls that are more fatal than any technical gap, and how to run both tracks without dropping one.
| Month | US track | China track |
|---|---|---|
| Jan-Feb | Spring internships close; first decision point — which target companies sponsor H1B | — |
| Mar | H1B lottery results (late Mar-early Apr); cap-exempt applications open | — |
| Jun-Jul | Early-round applications (字节/腾讯/阿里 equivalents: FAANG early programs) | 提前批 opens (Jul-Aug) — 字节/腾讯/阿里 lead |
| Aug-Oct | Fall recruiting interview peak; offers out Aug-Oct | 正式批 (Sep) → written tests + interviews Sep-Nov |
| Oct (mid) | Second decision point: compare offer progress on both sides; use one side's offer as leverage on the other | |
| Dec-Jan | — | Offers land in batches; 应届 window closes as graduation approaches |
How exactly does OPT work, and what are the hard rules?must-know
Standard OPT is 12 months, starting the day you graduate (not when you get your degree ceremony — your I-20 end date governs). STEM-designated degrees (CS/AI qualify) can add a 24-month STEM OPT extension, for 36 months total. Two rules that kill people: (1) the unemployment cap — once your OPT starts, you may not accrue more than 90 cumulative days of unemployment on standard OPT (the STEM OPT extension adds 60 more, for 150 total, and those extra 60 only become available once STEM OPT is approved). Exceeding the cap puts you out of F-1 status — not just a voided OPT. (2) The clock starts at graduation — if you wait 3 months after defending your thesis to "start looking," you've already burned a quarter of your OPT. Interns should also track CPT: cumulative CPT over 12 months consumes your OPT entirely. Do the math before accepting any RA or off-campus internship.
When and how should I think about the H1B lottery?must-know
The H1B cap lottery is in March, for a start date of Oct 1. The strategic mistake: waiting for a signed offer before checking whether the employer sponsors. The right sequence, starting 9-12 months before graduation: (1) build a target list with an explicit "sponsors H1B: yes/no/maybe" column (official career pages, Blind, level.fyi, and alumni are the sources); (2) prioritize companies with high selection rates or cap-gap eligibility when your timeline is tight; (3) if you miss, your fallbacks are cap-exempt employers (universities, non-profits, some research labs), the STEM OPT 24-month extension to enter again, or switching to the China track while your 应届 window still holds. The lottery result (April) to July is the golden window to re-plan the China track — the 提前批 just opened.
What does the US fall recruiting process actually look like?must-know
Standard loop: online application → phone screen (30-45 min, often behavioral + one technical question) → on-site loop (4-5 rounds: coding ×2, system design, product sense, values/behavioral) → offer. Total 2-6 weeks per company. For SWE/AI-adjacent roles the coding rounds are LeetCode medium-hard; AI roles increasingly add a machine-learning fundamentals round. Timing: applications open Jun-Jul, most interviews happen Aug-Oct, and offers go out in waves starting late August. Rejection is not final — referrals can keep your application alive, and many companies reopen roles in November. Two practical notes: the loop is scheduled in US business hours (which, if you're also doing China written tests, means Beijing late night/early morning — that's normal and HR coordinates it), and a strong GitHub with readable repos and commits is checked more than students expect.
Does holding a Chinese offer conflict with OPT?must-know
No legal conflict — you can hold both a US offer and a China offer simultaneously, and OPT status doesn't block joining a Chinese employer. The value to watch is the post-return identity window: with a master's degree and 1+ year of study abroad, you qualify for the overseas-talent fast track (落户 green channel) in Beijing/Shanghai/Shenzhen, typically with a 2-year return deadline. That window is worth more than the base salary difference in most negotiations — don't anchor on base alone. Also: if you've already worked a full year on US OPT before returning, some Chinese employers treat you as non-应届 (no longer a fresh graduate), forcing you into the more demanding social-recruiting (社招) track. Ask before you apply, not after you've finished the written test.
I missed the H1B lottery — is my US stay over?must-know
No. It makes staying more expensive, not impossible. The realistic paths, in order: (1) cap-exempt employers — universities, national labs, non-profits, some research institutes; a research or teaching-adjacent role can buy another year without the lottery; (2) STEM OPT extension — 24 more months, enter the lottery again (and again); (3) switch to the China track — at which point the decisive variable is how much 应届 window you have left. China's fresh-graduate window is measured in 届 (graduating cohort): a 2027 master's (graduating 2026.9-2027.8) can apply to the 2027 autumn cycle starting July 2026. Miss the window and you're in 社招, where "no domestic work experience" is penalized harder. So: lottery result in April, decision by July, applications rolling in the same month.
Will Chinese companies actually accept overseas students as 应届 (fresh grads)?bonus
The mainstream rule: yes, by expected graduation date — 2026.9-2027.8 graduation maps to the 2027 cohort, and most big-tech ATS have a dedicated field or entry point for overseas students. But two scenarios get rejected, and both are checkable in a 10-minute email before you apply: (1) the fuzzy zone — graduating, say, March 2027; some companies only count graduates from 2026.9 onward; (2) you already completed a year of US OPT full-time — some policies then disqualify you from 校招. Email the official recruiting address or your HR contact: "How is my overseas degree classified for 应届 status?" The cost is one email; the benefit is not wasting a written-test slot. Ask before, not after.
What actually differs between the US and China versions?must-know
Three differences that matter: (1) Project narrative. US version: "what I solved independently, GitHub link, reproducible" — US interviewers genuinely open the repo and read commits. China version: "business closed-loop, shipped impact, quantified numbers" — Chinese interviewers trust "it landed in production" before "the tech is deep." (2) Paper placement. US version: top-conference papers up top, it's a plus. China version: papers after projects — big tech trusts shipped systems; papers lead only on the talent-plan (人才计划) track. (3) Format. US: one page, no photo/gender/age (EEOC compliance). China: 1-2 pages, education first. One "tech-only" résumé applied to both markets scores about 70 on each.
I only have coursework projects and a RA — no US internship. Viable?must-know
Yes, and more viable than most think. The real China-side screening standard is project depth + interview performance, not "big-tech US internship" — that credential is hard currency on the US track and only a bonus on the China track. Your gap is "no domestic business context," and the fix is translation: rewrite "SOTA +3% on XX benchmark" as "designed XX for scenario YY; offline metric X→Y; ablation shows the gain comes from module Z," and pre-answer the follow-ups Chinese interviewers always ask — cost, latency, and how you'd evaluate it in production — by putting those three dimensions into your bullets. For the RA: emphasize systems you built from 0 to 1 (eval harnesses, data pipelines, training pipelines) over "published one paper." Add one self-built project with an eval set, numbers, a repo link, and a README in "problem → solution → result → reproduce" form. One project you can defend for three levels of follow-up beats three "participated in" lines.
How does the China-side AI interview loop differ from the US one?must-know
China: written/online coding test → 2-3 technical rounds (round 1: fundamentals + project deep-dive; round 2: system design + project stress; round 3: leader interview on potential and motivation) → HR round (salary + stability). Total 2-4 weeks. The differences that actually bite: project deep-dive is ~70% of the technical time (US loops weight system design and behavioral more), hand-written coding is more common, and interviewers are more direct — "which exact part did you build?" is the standard opener. The highest-ROI preparation: for every project on your résumé, drill three levels of follow-up (what you claimed → why that design → where it breaks), rather than grinding more LeetCode.
How do I schedule interviews across the 15-16 hour time difference?must-know
West Coast to Beijing is 15-16 hours; the workable window is 7-9 AM Pacific = 10 PM-midnight Beijing. Written tests are self-scheduled — no constraint. For interviews, book Pacific mornings and confirm in advance: "This is late night Beijing time — does that work?" Big tech HR coordinates this routinely for overseas candidates. Same logic applies to any 1v1 résumé coaching or mock interview (WeChat/Tencent Meeting). The real risk is not the clock — it's that China's 提前批 opens in Jul-Aug, so "I'll get to it in October when I'm free" means more than half the window is already gone.
What's the actual salary gap between US and China AI roles?bonus
Rough 2026 magnitudes, total compensation (base + equity + signing, pre-tax): US first-tier AI roles for a master's, Bay Area/Seattle: $150K-250K. China big-tech AI fresh-master's: ¥400K-700K, with top talent plans reaching ¥1M+ (see the big-tech talent program comparison for the per-company breakdown). After purchasing-power adjustment the gap narrows to 1.5-2×, and you should price in China's hidden returns: hukou (household registration) value in Beijing/Shanghai/Shenzhen, continuous social insurance, life radius, and the one-time 应届 window. Money-only math says US; total-cost math depends on your case — which is exactly why the two-track strategy exists: apply to both, and let the offers negotiate against each other.
Step 1: finalize both résumé versions before July
US version (1 page, projects + GitHub first, English) and China version (1-2 pages, business-translated, education first). The bar: every line survives three levels of follow-up (how you got it → why that design → where the boundary is). If you're not sure you've met the bar, one 1v1 pass — remote, timezone-coordinated — is faster than asking ten people in group chats.
Step 2: build the target-company identity table before August
One row per company: sponsors H1B (US track) / how they classify your 应届 status (China track) / when their early round opens. Sources: official career pages, a direct email to the recruiting team (overseas students usually have a dedicated entry point), and alumni with recent offers. This table decides what you apply to every week starting in July — and it takes an afternoon to build.
Step 3: prepare interviews as projects, not question banks
Pick the 2-3 projects on your résumé and prepare each as: design motivation → key trade-offs → verifiable results (with the exact metric definition) → failures and boundaries. For fundamentals, the LLM interview question checklist plus the per-direction guides (RAG / Agent / fine-tuning / inference) cover the high-frequency ground — prepare only the directions your résumé actually claims; anything you list, you must be able to defend for three levels.
Two decision points: Feb-Mar (which companies to apply to, whether they sponsor H1B) and mid-October (offer progress on both sides). The windows overlap in Jul-Oct; the most robust play is applying on both tracks with two résumé versions, using whichever offer lands first as leverage on the other side.
12 months of standard OPT from graduation day, plus a 24-month STEM OPT extension for STEM degrees (CS/AI qualify) — 36 months total. Hard rules: the 90-day cumulative unemployment cap (150 days once STEM OPT is approved), and CPT over 12 months consuming OPT. The clock starts at your I-20 end date, not when you start looking.
Three paths: cap-exempt employers (universities, non-profits, research labs); the 24-month STEM OPT extension to re-enter the lottery; or switching to China's autumn recruiting while your 应届 window holds. The April-to-July stretch after the result is the golden window to re-plan the China track, because 提前批 just opens.
No. China-side screening weights project depth and interview performance over "US big-tech internship." The gap to close is business context: translate academic results into shipped-system language and pre-answer cost/latency/evaluation questions in your résumé bullets.
Yes, no legal conflict — OPT status doesn't block joining a Chinese employer. Compare them in mid-October: total comp, hukou/落户 value, the 应届 window on the China side, and sponsor risk on the US side. One offer strengthens your negotiation on the other.
