Ask HN: H1B visa holder can launch a monthly subscription app?

Hi, I'm working on an app that will have monthly subscription for users to use. I'm using Stripe for the subscription payment system and noticed that I need EIN number to actually activate my Stripe account to start correct payment. After some googling, it seems to be possible to get an EIN number as a H1B visa holder but what to make sure that I'm not missing out anything. What is the best way for me to get the Stripe account activated and launch my app? Thank you in advance!
