It's risky to relocate the servers in another country. You will have to obey the other country's laws, but the US gov will still claim jurisdiction if the staff and/or owner is in the US. The US will even claim jurisdiction as soon as you use a ".com" domain [1]
Of course the hosting nation will also claim jurisdiction. So relocating your servers to one country while staying in another will expose you to two national laws as well as any international agreements between these nations.
