Hi, I worked on a H1B from 2008 until 2009, then from 2013 until 2015 for a different company, all in all I have used very close to 3 years. 1- Can I reactivate my H1B at any moment to work for a company in the US for another 3 years ? 2- On a H1B is it possible to work in the US for 1 week per month and the rest remotely from abroad? Does it have to be at least 2 weeks per month? 4 weeks per month? Thanks so much for doing this!
