As answered by people managing Composer and GCInterview.
GCInterview's answer:
GCInterview is the only interview prep tool built specifically for marriage-based green card (I-485) applicants. Instead of generic immigration info, it simulates the actual USCIS interview experience with an AI-powered officer who uses real interrogation techniques, including Stokes (separated room) interview practice. It was built by a couple who went through the process themselves.
GCInterview's answer:
Most competitors offer static lists of questions or general immigration advice. GCInterview gives you a realistic mock interview with an AI officer who adapts to your answers, catches inconsistencies, and uses the same pressure tactics real officers use. It also includes a Stokes interview simulator where couples practice being questioned separately - something no other tool offers. Plus, it's a one-time $19 payment, not a subscription.
GCInterview's answer:
Couples preparing for a marriage-based green card interview at a USCIS field office. Typically one partner is a US citizen (the petitioner) and the other is an immigrant (the beneficiary). They're usually anxious about the interview and want to feel prepared and confident before their appointment.
GCInterview's answer:
We built GCInterview while preparing for our own marriage-based green card interview. We couldn't find any tool that actually simulated the interview experience - everything was just blog posts with generic question lists. So we built what we wished existed: a realistic practice tool with an AI officer, evidence checklists, and Stokes interview prep. After using it for our own interview, we decided to make it available to other couples going through the same process.
GCInterview's answer:
React, Vite, Supabase (authentication and database), Stripe (payments), and Claude AI by Anthropic (powering the mock interview officer).
GCInterview's answer:
GCInterview serves individual couples preparing for their USCIS marriage-based green card interviews. As a consumer product, we focus on helping everyday couples rather than enterprise clients. We've helped couples from dozens of countries prepare for interviews at USCIS field offices across the United States.

I'm embarrassed I never took the time to understand Composer until now. I have been preaching for a long time to start each PHP project with Composer, even when the project is not going end up on Packagist. - Source: dev.to / 4 months ago
