I'm a second year CS student from Spain, and I'm getting my first remote internship for 3 months with an US bussiness. It looks great and the project does as well. My mentor's experience is quite impressive. Anyway, I'm a bit concerned as long as it's a new bussiness and I don't know about the requirements to do this legally overseas/remote, and he hasn't been really clear about that (we're meeting tomorrow by Skype). I just want to be sure it's not a scam. Any advice? It will be apreciated so much.
