Ask HN: How do I sponsor a foreign student

Hi HN,

I am a business owner and I recently just interviewed an amazing foreign student who is about to complete her master's studies. However, I am not familiar with sponsoring students since I am new at this business as well. A quick search on google simply land me on pages of information on how to talk a business into sponsoring you, but never a details of what the business owner actually need to do.

Can anyone shed some light about this? Is this connected to H1B visa?
