Thanks mrbtx
My spouse has been posted overseas by her US big brand parent company, to build better relationships and grow business with the multinational and overseas clients of her office.
As it was COVID, this made a lot of sense as travel was off. They will ask her to stay until end of 2023. She still gets salary from the US but is based in Europe. Her company is happy to document what they asked her to do in a formal letter, but we want to make sure we don't miss anything for the 319(b) eligibility.
