The General Application Process
-
Employer Sponsorship: For most visas (like H-1B, L-1), a U.S. employer must first sponsor you by filing a petition with USCIS.
-
Labor Certification: For some green cards (EB-2, EB-3), the employer must prove there are no qualified U.S. workers available for the position.
-
USCIS Petition: The employer files the appropriate form (e.g., I-129 for non-immigrant visas, I-140 for immigrant petitions).
-
Consular Processing or Adjustment of Status: If you are outside the U.S., you apply for the visa at a U.S. embassy/consulate. If you are inside the U.S., you may “adjust your status.”
Choosing the right visa depends on your qualifications, your employer, and your long-term goals. For the most accurate and personalized guidance, always consult the official USCIS.gov website or an experienced immigration attorney.
