I have a life in country A (house, work, wife ..etc). My opportunities are limited to companies having LLC in my country or B2B contracts. If I were to accept a job in country B I would (in 9/10 scenarios) need to move to that country and adjust to the local culture and language. I had a friend with korean wife who was in Germany and then Belgium each for couple of years. The whole family was suffering from the constant need of adaptation to local languages and eventually they ended up going to Canada.
