What San Mateo Employers and Beneficiaries Can Access

H-1B Specialty Occupation Petition Filing

We prepare and file Form I-129 petitions for specialty occupation positions requiring a bachelor's degree or higher in a specific field — including software engineering, data science, financial analysis, and biotechnology roles common among San Mateo employers. Each petition includes a certified Labor Condition Application (LCA) filed with the U.S. Department of Labor, detailed specialty occupation evidence demonstrating the position's educational requirements, and beneficiary credential evaluation. Initial consultation available within 48 hours.

H-1B Visa Extension and Amendment

For beneficiaries already in H-1B status, we handle three-year extensions filed before status expiration and material change amendments required when job duties, work location, or employer changes occur. San Mateo employers must file an amended petition before any material change takes effect — failure to do so can result in status violations. Learn more about our H-1b Visa Process San Diego and H-1b Visa Guidance services.

Request for Evidence (RFE) Response

USCIS issues Requests for Evidence in approximately 35% of H-1B petitions, most commonly challenging the specialty occupation classification or the beneficiary's credential equivalency. We draft comprehensive RFE responses within the statutory deadline, including supplemental expert opinions, employer documentation, and case law citations addressing USCIS concerns.

What If My San Mateo Employer Files an H-1B Petition but I'm Currently Outside the U.S.?

If you are outside the United States when your employer files the H-1B petition, you will undergo consular processing after USCIS approves the I-129. This means your employer files the petition in San Mateo, receives the Notice of Approval (Form I-797), and then you schedule a visa interview at a U.S. consulate in your home country. The consular officer adjudicates your visa application separately from the approved petition — checking for inadmissibility grounds and verifying your credentials. Processing timelines vary by consulate; high-volume posts in India and China average 60–90 days from interview to visa issuance. Once the visa is issued, you may enter the U.S. up to 10 days before your petition start date.

What If My H-1B Petition Is Denied While I'm Already Working in San Mateo on H-1B Status?

If USCIS denies an extension or amendment petition while you are already in valid h-1b san mateo status, you do not immediately fall out of status — your existing H-1B approval remains valid until its expiration date on your Form I-797. However, you cannot continue working for the petitioning employer under the denied petition. Your options include filing a motion to reopen or reconsider, filing an appeal to the Administrative Appeals Office, or having your employer file a new petition with corrected evidence. If your current status expires before a new petition is approved, you must stop working and either leave the U.S. or change to another status.

What If My San Mateo Employer Wants to Transfer My H-1B to a New Position in a Different California City?

If your San Mateo employer transfers you to a new work location — even within California — and the new location is outside the geographic area covered by your original Labor Condition Application, your employer must file an amended H-1B petition before you begin work at the new site. The amended petition requires a new LCA certified for the new work location and updated wage data demonstrating compliance with prevailing wage requirements in the new area. You may begin working at the new location once USCIS receives the amendment, under the portability provision — you do not need to wait for approval — but the petition must be filed before the transfer occurs.

What If I Lose My Job While on H-1B Status in San Mateo?

If your employment terminates while you are in H-1B status, you enter a 60-day grace period (or the remaining time on your I-94, whichever is shorter) during which you remain in lawful status but cannot work. During this period, you may search for a new employer willing to file a transfer petition, change to another nonimmigrant status (such as B-2 visitor or F-1 student), or depart the U.S. If you find a new employer who files an H-1B transfer petition during the grace period, you may begin working for the new employer once USCIS receives the petition, even before it is approved. If 60 days pass without a filed petition or status change, you accrue unlawful presence and must leave the U.S.

Immigration Attorney vs. Online Filing Services vs. Employer In-House Counsel

San Mateo employers and H-1B beneficiaries face three primary options: hiring an independent immigration attorney, using an online DIY filing platform, or relying on employer in-house counsel. Here's the honest answer: online platforms are cost-effective for straightforward cases with no prior denials, no RFEs, and employers who fully understand LCA wage requirements — but they provide no representation if USCIS issues a challenge. In-house counsel at large technology firms handle high volumes efficiently, but beneficiaries have no independent representation if their interests conflict with the employer's. Independent immigration counsel like Law office of Peter Darwin Chu represents the beneficiary or employer directly, provides advocacy in RFE responses and appeals, and owes fiduciary duties to the client — not the platform or company.

Option	Upfront Cost	RFE Response	Beneficiary Advocacy	Bottom Line
Independent Attorney	$3,000–$6,000	Included in representation	Direct attorney-client relationship	Best for complex cases, prior denials, or beneficiaries seeking independent counsel
Online Platform	$500–$1,500	Additional fee or not available	No individual representation	Suitable only for straightforward first-time filings with compliant employers
Employer In-House Counsel	Employer-paid	Handled by employer's attorney	Represents employer, not beneficiary	Efficient for large firms, but no independent advocacy for worker
No Attorney (Pro Se)	Filing fees only	Self-drafted	None	High denial risk — not recommended for H-1B specialty occupation cases
