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 โ€” daily life, finances, relationship history, family, home, and immigration status โ€” compiled from real interview reports and organized by how often officers ask them.
  • AI Mock Interview โ€” 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 โ€” 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 โ€” before an officer finds it.
  • 37-item evidence checklist โ€” 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 โ€” unlimited AI mock interviews, the complete question bank, and Separate Rooms โ€” 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.

assertpy features and specs

  • Fluent API
    Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
  • Chainable Assertions
    It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
  • Comprehensive Assertion Methods
    The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
  • Extensibility
    Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
  • Pythonic
    Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Possible disadvantages of assertpy

  • Learning Curve
    Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
  • Limited by Python Version
    The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
  • Performance Overhead
    The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
  • Less Community Support
    Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
  • Dependency Management
    Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.

Analysis of GCInterview

Overall verdict

Questions & Answers

As answered by people managing assertpy and GCInterview.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

GCInterview's answer:

React, Vite, Supabase (authentication and database), Stripe (payments), and Claude AI by Anthropic (powering the mock interview officer).

Who are some of the biggest customers of your product?

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.
