I don't know you, but I strongly feel that you are making the wrong decision. Let's go over the points... Your friend pitched a startup idea. Based on your wording, it sounds like it is more an idea than an actual company. Either way, unless your friend's startup has the legal resources to sponsor a H1B visa and the financial capability to pay you a prevailing wage, you run the risk of not being able to transfer your visa. The government agency can reject your visa transfer, as well. By declining the offer, you are putting yourself in jeopardy of losing your ability to work in the country. I assume you are not married, but for the sake of this response, let's assume you are. What would your wife think about this? Don't be so selfish, imagine that others would be affected. You are assuming that you will be able to work at the startup legally (H1B transfer). I don't believe you can assume this. Does your friend even know what is involved in sponsoring a H1B? Major tech companies have dedicated departments for managing the H1B process for their employees. Good luck!
