What If My H-1B Cap Registration Was Selected But My Employer in Davis Hasn't Filed Yet?

If your employer's H-1B registration was selected in the annual lottery but the petition has not been filed, you are facing the April 1 through June 30 filing window. Missing this deadline permanently forfeits your selection for that fiscal year. We expedite petition preparation for Davis employers by completing the Labor Condition Application within 7 business days, assembling all required specialty occupation evidence, and filing electronically with USCIS before the deadline. Even if you are contacting us in late May or June, same-week filings are possible.

What If I'm Already Working in Davis on OPT and Need to Transition to H-1B?

F-1 students on Optional Practical Training in Davis can transition to H-1B status through a cap-subject petition if selected in the lottery, with an October 1 start date if approved. The cap-gap extension automatically extends your work authorization and F-1 status through September 30 if your employer files the H-1B petition before your OPT expires. We coordinate timing to ensure uninterrupted work authorization for Davis OPT holders, and advise on STEM OPT extensions when cap-subject petitions are not selected.

What If My Davis Employer Wants to Change My Job Title or Salary While I'm in H-1B Status?

Material changes to job duties, title, work location, or salary require an H-1B amendment petition filed before the change takes effect. In Davis, this most commonly affects university employees transitioning from postdoctoral roles to faculty positions, or startup employees whose roles evolve significantly. We determine whether the change requires a new Labor Condition Application and amended petition, or qualifies as a minor change. Failing to file an amendment when required can jeopardize your H-1B status and green card eligibility.

What If I Received a Request for Evidence on My Davis H-1B Petition?

Requests for Evidence (RFEs) on H-1B petitions typically challenge specialty occupation classification, beneficiary qualifications, or employer-employee relationship. In Davis, university and research institution petitions face RFEs questioning whether the position requires a bachelor's degree in a specific specialty. We have 30-90 days to respond depending on the RFE type, and our response must directly address every USCIS concern with expert opinions, industry documentation, and credential evaluations. An RFE is not a denial — over 70% of properly responded RFEs result in approval.

Choosing an H-1B Immigration Lawyer vs. Online Petition Services

Davis H-1B petitioners choose between full-service immigration attorneys, online document preparation platforms, and employer in-house counsel. Online platforms offer lower upfront costs ($500-$1,500) but provide no legal representation if USCIS issues a Request for Evidence, and cannot advise on specialty occupation classification nuances or wage level determinations. Employer in-house counsel may lack immigration-specific experience and current knowledge of California Service Center adjudication trends. Here's the honest answer: H-1B petitions are not a commodity service — they are adversarial legal filings reviewed by adjudicators trained to find grounds for denial. A petition prepared without attorney oversight that results in denial costs the employer the filing fee ($460-$2,500 depending on employer size) and the opportunity cost of that fiscal year, and forces the beneficiary to leave the United States or change status.
