I recently finished my undergrad and I am an international. This may not be the most helpful comment, but hopefully it will make you consider other options.

I know there is a certain appeal to starting a startup in Silicon Valley and going through the motions of being an entrepreneur, but you don't have to be based in the US to be a successful tech entrepreneur. Virtually any big VC that invests in the US also has an international investment arm. You can hire remote talent to work on your product, or even talent in countries other than the US. In fact, I hypothesize that you may be able to find better talent elsewhere because job hopping isn't as common in other parts of the world.

Canada has an excellent startup visa program and it is the closest thing you will find to actually doing a startup in the US.

Why do you want to start your company in the US?
