Path to Legal Residency for a Mexican National in the U.S. Illegally for 4 Years

There is no automatic path; options depend on individual circumstances. General steps:

1. Identify Eligible Visa Category: Family-based (e.g., U.S. citizen spouse/parent/child over 21), employment-based, asylum, U/T visa (crime/trafficking victims), DACA (if eligible), or other relief.
2. File Petition: Qualifying relative/employer files with USCIS (e.g., I-130, I-140).
3. Adjustment of Status (if in U.S.) OR Consular Processing (if abroad):
   • Adjustment (I-485) possible only if entered legally or qualify under §245(i) (petition filed before Apr 2001). Unlawful entry generally bars adjustment.
   • Consular processing requires leaving U.S., triggering 3/10-year unlawful presence bars unless waiver (I-601A) approved.
4. Interview, Medical, Fees: Attend interview, pass medical exam, pay all fees.
5. Approval → Green Card.

Critical: Unlawful presence >1 year triggers a 10-year bar upon departure. Consult an experienced immigration attorney before any action.
