Where do I mail Form I-129?

The I-129 filing address depends on the visa classification (H-1B, L-1, O-1, TN, etc.), whether the petition is cap-subject, and sometimes the state of the primary worksite. USCIS publishes the authoritative 'Direct Filing Addresses for Form I-129' chart at uscis.gov/i-129-addresses. For lottery-selected H-1B cap petitions, the correct address is printed on the registration selection notice — always use that address. Filing at the wrong address can cause rejection.

What is a direct filing address?

A direct filing address means you send the petition directly to the USCIS service center that will adjudicate it, rather than to a lockbox facility that forwards it. Form I-129 historically used direct filing to the Texas or California Service Centers. USCIS has been migrating I-129 workloads to lockbox intake for some classifications — which is why checking the current chart before every filing matters.

Can I file Form I-129 online?

Yes — for many classifications. USCIS opened online I-129 filing for H-1B cap petitions (FY 2025 onward) and has been expanding to other H-1B petition types through myUSCIS organizational accounts. Online filing eliminates the address question entirely, provides instant receipt confirmation, and allows online I-907 premium processing requests. Check uscis.gov for which classifications currently support online filing.

What happens if I mail the I-129 to the wrong address?

USCIS typically rejects petitions filed at the wrong location and returns them with the fee — costing you weeks. For cap-subject H-1B petitions this can be fatal: if the rejection and re-filing push you past the 90-day filing window after selection, the petition can be refused as untimely. Always verify the address against the current USCIS chart (or your selection notice) on the day you mail, and use trackable delivery.

Does premium processing change where I file the I-129?

No — when filing I-907 (premium processing) together with the I-129, both go to the same address as the I-129 alone. If you're upgrading an already-pending I-129 to premium, send the I-907 to the service center currently holding the case (shown on your receipt notice transfer notices, if any). Premium processing guarantees a decision in 15 business days for most I-129 classifications.

Which service center will process my H-1B petition?

USCIS distributes I-129 H-1B workloads mainly between the Texas Service Center and California Service Center, generally split by the state of the beneficiary's primary worksite, with workload balancing transfers possible at any time. Your receipt notice (Form I-797C) shows which center has your case — the receipt number prefix tells you: WAC = California, SRC = Texas, EAC = Vermont, LIN = Nebraska, IOE = filed online.
