H-1B Texas Service Center (TSC / SRC) Guide (2026)
The Texas Service Center processes H-1B petitions for employers in the southern US states, including major Texas tech and energy employers.
Which Employers File at TSC?
The Texas Service Center (TSC), whose receipt numbers begin with SRC (Southern Receiving Center), handles H-1B petitions for employers in: AL, AR, FL, GA, KY, LA, MS, NC, NM, NY, OK, SC, TN, TX. Note that USCIS periodically adjusts service center assignments — some jurisdictions have shifted between centers in recent years.
TSC Processing Times
TSC standard H-1B processing: 3-5 months, consistent with other service centers. Premium processing: 15 business days from I-907 receipt. Texas-headquartered employers (Dell, AT&T, ExxonMobil, Texas Instruments) primarily file at TSC. The SRC receipt prefix (SRC25-xxx-xxxxx) confirms TSC adjudication.
TSC and Energy Sector H-1B
A distinctive feature of TSC caseload is the high volume of energy sector H-1B petitions. ExxonMobil, Chevron (corporate), Shell (Americas HQ), Halliburton, and hundreds of O&G engineering firms file at TSC. Petroleum engineer H-1B petitions have high approval rates because the specialty occupation standard is clearly met by PE licensing requirements.
TSC RFE Patterns
TSC RFE patterns closely mirror national averages. Texas IT services companies (which have significant H-1B volume from staffing firms) see higher RFE rates than product companies. Third-party placement cases at TSC should include robust end-client letters, itinerary statements, and employer-employee relationship evidence.
Frequently Asked Questions
What receipt number prefix does the Texas Service Center use?
TSC receipt numbers begin with SRC (Southern Receiving Center): SRC25-xxx-xxxxx for FY2025 petitions. Check the first three letters of your I-797 receipt notice to determine which center is adjudicating your case.
Which major employers file H-1B at the Texas Service Center?
Major TSC filers include Dell Technologies (Round Rock), AT&T (Dallas), Texas Instruments (Dallas), ExxonMobil (Spring), Hewlett Packard Enterprise (Houston), Cognizant (Allen/Dallas), Infosys (Texas), Tata Consultancy Services (TX), and Amazon (Texas ops). Florida, Georgia, and North Carolina employers also file at TSC.
How do I check my SRC case status?
Go to egov.uscis.gov and enter your SRC receipt number. Sign up for notifications. For cases outside normal processing times, submit an online service request. Do not call USCIS before the posted processing time has elapsed.
Does TSC adjudicate differently than CSC or VSC?
USCIS policies are national and applied consistently across service centers. Differences in reported outcomes reflect the types of cases each center receives (industry mix, petition quality) rather than center-specific policies.
