Questions & Answers

As answered by people managing Amberbird and StackMail.

What's the story behind your product?

Amberbird's answer

It started from a simple observation: people on H-1B, F-1/OPT, or green card timelines carry a specific kind of 2am fear, a question like "does my OPT clock keep running if I leave the country?" where getting it wrong doesn't cost money, it costs years. The only options were an expensive lawyer or a confident stranger on a forum. Amberbird was built to close that gap with something in between: honest, sourced, and willing to say "this needs a lawyer" when that's the true answer.

What makes your product unique?

Amberbird's answer

Most AI immigration tools are built to always answer, and that confidence is exactly what makes them risky in a domain where a wrong answer can cost someone their status. Amberbird does two things differently: every claim it makes is tied to the specific USCIS source it came from, so you can verify it yourself, and it's built to recognize when a question depends on individual legal judgment and refuse to guess, referring you to a licensed attorney instead. The refusal is treated as a core, tested feature, not a fallback.

Why should a person choose your product over its competitors?

Amberbird's answer

Right now the choice for most people is a $400-an-hour immigration lawyer or an anonymous forum thread, both of which have real downsides: one is expensive for a simple question, the other is free and occasionally catastrophic. Amberbird sits between them. It handles the clear, common questions with sourced, verifiable answers, so you're not paying attorney rates for something the government already published, and it's honest about the edge of its own competence instead of bluffing through the questions that genuinely need a human.

How would you describe the primary audience of your product?

Amberbird's answer

People navigating US immigration who have a question, not a case: international students on F-1/OPT status, H-1B visa holders and their employers, and individuals working toward an employment-based green card. Typically people who don't yet need to retain an attorney but can't find a reliable, fast answer anywhere else.
