I am a self-taught software developer been working online for a while. I've been building a software for an employee in a company and getting paid through Paypal.
The company now decides to buy the product, employ me full-time (remote) however they'd like me to go for a meeting to the US.
What is the best way to get a visa for it? Should they invite me or write some kind of an invitation letter? Should I apply to it by my-self?
Some info about me:
The university I finished is completely another field (will that rise an eyebrow?)
I assume they'll cover all my expenses being there.
I am a UK citizen but haven't lived there for the past 4 years. Been traveling/working from home in Europe.
