You apply, you pass the interviews, you get the offer. You think you are safe. You are not.
The tech industry has a systemic problem with how it talks about immigration. Startups use "visa sponsorship" as a recruiting tool, but HR departments rarely explain the brutal mathematics of the process to junior candidates. If you are relying on an H-1B to stay in the country, you need to understand the reality.
The Lottery Reality
Here is the fact that recruiters gloss over: Sponsoring a visa does not mean you get a visa. It means the company will buy you a lottery ticket.
Every year, the US government issues 85,000 H-1B visas. In recent years, they have received over 400,000 applications. This means that even if a startup spends $5,000 on lawyers and perfectly files your paperwork, you have roughly a 20% to 30% chance of actually getting the visa.
If you are on OPT (Optional Practical Training), you usually have three years (if STEM) to play this lottery. If you don't win after three tries, you have to leave the country. Period.
The Startup Risk Factor
Big Tech companies (Google, Meta, Amazon) have massive immigration departments. They know exactly how to handle the H-1B process, and if you lose the lottery, they have fallback plans. They will transfer you to their office in Vancouver, Canada, or London, UK, and try again next year.
Most startups do not have this luxury.
If you join a Series A startup and lose the H-1B lottery on your final attempt, the startup cannot transfer you to Canada. They don't have a Canadian entity. Your employment will simply be terminated. I have seen brilliant engineers forced to pack up their apartments in 30 days because the startup had no backup plan.
Questions You Must Ask Before Accepting
If you are an international candidate interviewing at a startup, you cannot afford to be polite about immigration. You must ask aggressive, specific questions during the offer stage.
1. "Have you successfully sponsored an H-1B before?"
If the answer is no, be very careful. You do not want to be the guinea pig for an HR person who is figuring out immigration law on the fly. Missing a filing deadline by one day ruins your life.
2. "What immigration law firm do you use?"
If they say "we do it in-house" or "we use LegalZoom," run away. You want to hear the name of a reputable immigration firm (like Fragomen or BAL) or a modern platform like Envoy or Deel.
3. "What is the backup plan if I don't get selected in the lottery?"
This is the most critical question. Do they have an Employer of Record (EOR) setup to hire you remotely in your home country? Are they willing to sponsor an O-1 (Extraordinary Ability) visa if you qualify? If their answer is "we'll cross that bridge when we come to it," they do not understand the gravity of the situation.
The Alternative: Cap-Exempt Institutions
If you are down to your last year of OPT and you cannot risk the lottery, you need to look at "Cap-Exempt" employers. Universities, non-profit research organizations, and government research labs do not have to go through the H-1B lottery. If they sponsor you, you get the visa.
The pay will be lower than a VC-funded startup. But it buys you time, stability, and a guaranteed path to stay while you figure out your next move.
