What Sunnyvale Residents Can Access

H-1B Initial Petition Preparation

We prepare Labor Condition Applications (LCA), Form I-129 petitions, and specialty occupation evidence packages that satisfy USCIS's four-part test under Matter of Dhanasar standards. For Sunnyvale tech employers, this includes degree equivalency analyses, prevailing wage documentation, and employer-employee relationship evidence. Initial petition consultations review your job duties, credential evaluation, and filing timeline before the April cap season. H-1B – Specialty Occupation Visas provides detailed process guidance.

RFE and Denial Response

When USCIS issues an RFE challenging specialty occupation classification or employer-employee relationship, our H-1B specialty occupation visa Sunnyvale team drafts technical responses with expert opinion letters, industry wage surveys, and organizational documentation. We have responded to over 200 H-1B RFEs across semiconductor, software engineering, and data science roles — addressing level determination issues and itinerary requirements specific to California employers.

H-1B Extension and Amendment Filings

H-1B extensions must be filed before the current approval expires, and material changes to job duties, work location, or salary trigger amendment requirements under the portability provisions of AC21. Our firm handles same-employer extensions, transfer petitions under INA 214(n), and concurrent H-1B filings for Sunnyvale clients changing roles mid-approval period. H-1B Visa Guidance outlines extension timelines and compliance obligations.

What If My Sunnyvale Employer Receives an H-1B Site Visit from USCIS?

USCIS conducts unannounced site visits under its Administrative Site Visit and Verification Program (ASVVP) to verify employer-employee relationships and job duties. If your Sunnyvale employer receives a site visit, they must provide access to the worksite, produce the public access file (PAF) containing the LCA and wage documentation, and answer investigator questions about your role and supervision. Refusal to cooperate can result in petition revocation. Contact immigration counsel immediately upon notice — we advise employers and beneficiaries on compliance obligations, document production, and follow-up response procedures to protect petition status.

What If I Need to Change Employers While on H-1B in Sunnyvale?

H-1B portability under INA Section 214(n) allows you to begin work for a new Sunnyvale employer as soon as they file a non-frivolous H-1B transfer petition — you do not need to wait for approval. However, if USCIS denies the transfer petition, your employment authorization ends immediately and you must stop working. The new employer must file a complete I-129 with LCA, and you remain in valid H-1B status during adjudication as long as the petition was filed before your current H-1B expired. Our firm files transfer petitions with premium processing when clients need immediate work authorization certainty for new Sunnyvale employers.

What If My H-1B Petition Is Selected in the Lottery but My Employer Hasn't Filed the I-129 Yet?

Selection in the H-1B cap lottery (conducted each March for the following fiscal year) does not guarantee petition approval — your employer must file Form I-129 by the June 30 deadline stated in the selection notice. If your Sunnyvale employer delays filing or decides not to proceed, you lose that lottery selection and must re-register the following year. We advise beneficiaries selected in the lottery to confirm employer intent immediately, provide all required documents within two weeks, and ensure the I-129 is filed by mid-June to allow time for RFE responses before the September 30 deadline.

What If USCIS Issues an RFE Questioning My Job Duties as a Specialty Occupation?

An RFE challenging specialty occupation classification typically requests additional evidence that your role requires a U.S. bachelor's degree or higher in a specific specialty as a minimum entry requirement. For Sunnyvale tech roles, USCIS frequently questions software developer, business analyst, and project coordinator positions where job duties appear generalized. Our response strategy includes detailed technical duty breakdowns, organizational charts showing your position's complexity, industry expert opinion letters, and Department of Labor data demonstrating degree requirements for your Standard Occupational Classification (SOC) code. Response deadline is typically 87 days — do not attempt a self-prepared response.

Why Sunnyvale Residents Choose Law Office of Peter Darwin Chu Over DIY Filing or Generic Immigration Mills

You have three options when facing an H-1B petition: (1) employer-prepared DIY filing using online templates, (2) high-volume immigration service mills that process hundreds of cases monthly with minimal attorney involvement, or (3) dedicated immigration counsel who reviews every petition before submission.

Here's the honest answer: H-1B petitions prepared without experienced legal review face RFE rates 3–4 times higher than attorney-prepared filings, according to USCIS stakeholder data. Generic immigration mills assign paralegals to draft your petition and route it to an attorney for signature review only — you never speak to the attorney who signs your case. Law office of Peter Darwin Chu limits caseload to ensure every H-1B petition receives direct attorney review of job duties, credential evaluation, and evidentiary support before filing. We do not use petition templates — every filing is drafted to the specific role, employer structure, and beneficiary background.
