GCInterview (Green Card Interview Prep) is a dedicated practice tool for the USCIS marriage-based green card (I-485) interview.

What it includes

• 383 real interview questions across 13 categories — daily life, finances, relationship history, family, home, and immigration status — compiled from real interview reports and organized by how often officers ask them.
• AI Mock Interview — practice with a simulated USCIS officer that asks adaptive follow-up questions based on your actual answers, rather than reading from a fixed script.
• Separate Rooms (Stokes) mode — the feature no other tool offers. In a Stokes interview, USCIS separates spouses and asks each the same questions, then compares the answers. Separate Rooms recreates this: each partner answers 116 real question pairs independently on their own phone, and the app shows you every mismatch — before an officer finds it.
• 37-item evidence checklist — track bona fide marriage proof, with substitutes for documents you don't have (no joint lease, no joint account, recently married).
• Free guides on interview day, post-interview timelines, RFEs, second interviews, and what happens if you fail.

Who it's for

Couples preparing for a marriage-based green card interview. In 2026 USCIS interviews nearly all I-485 applicants and separates spouses more often than in prior years, so preparation matters more than it used to.

Languages: English and Spanish.

Pricing: The question database and guides are free to browse. Full access — unlimited AI mock interviews, the complete question bank, and Separate Rooms — is a $19 one-time purchase. No subscription.

Built by a couple who went through the I-485 process themselves after finding that existing resources were either scattered free listicles or $300+ attorney consultations.
