Immigration Pathways

The United States immigration system is governed by the Immigration and Nationality Act (INA), codified at 8 U.S.C. sections 1101 through 1537. U.S. Citizenship and Immigration Services (USCIS), part of the Department of Homeland Security, processes most applications for visas, green cards, and naturalization. The Department of State handles visa issuance at consulates abroad, and the Department of Labor is involved in employment-based immigration through the labor certification process.

There are two broad tracks: temporary (nonimmigrant) visas for work, study, or visits, and permanent immigration leading to a green card and eventually citizenship. The system is category-based, with annual numerical limits (caps) on many visa types. Family-based and employment-based immigration each have separate preference categories with different wait times. Some categories have backlogs stretching decades, particularly for applicants from high-demand countries like India, China, Mexico, and the Philippines.

Fees are substantial. A typical employment-based green card process can cost $5,000 to $15,000 or more in government filing fees alone, not counting legal fees. Naturalization costs $725. USCIS publishes a fee schedule at uscis.gov/fees, and fee waivers are available for certain applicants based on income under 8 C.F.R. section 103.7.

Processing times vary widely. USCIS publishes estimated processing times at egov.uscis.gov/processing-times. Premium processing (Form I-907) is available for certain petition types for an additional $2,805 fee, guaranteeing a response within 15 business days.
