I'm a co-founder of Startup that is operating in the US for the last 5 years, we started it with my other co-founder (who is a US National)while i was on J1 visa, my visa expired and i had to come back to my country luckily for me i am the technical founder so most of my work can be done remotely, how ever we've been thinking on my relocation but we do not know the steps to follow can you give us any advice or resource we can follow?
