India has laws, you can visit there, but you cannot work there. They don't want US Citizens working there, many have found this out when applying for jobs that moved over there. Or so I have heard.

Our government and businesses don't have that kind of laws or rules. We let anyone who wants to work to work regardless of what citizenship they hold in what country.

Thailand has laws that say a Non-Thai person cannot own land or property there. Only Buddists are allowed in Government. Anything imported, like a car, gets a pretty steep import tax as high as 300%.

You have to see what laws apply to what country you want to work at. You may hit an Immigration tax, or be unable to own property, or not be allowed to work, or only allowed to work if you become a citizen there and swear off US Citizen status.
