If I work in Japan, is it easy to get an American visa from Japan?

If it is a tourist visa, it is relatively easier than in China. You must download a form for booking a single interview from the website of the American Embassy. Very detailed ... all in English, but most of them are true or false questions. You can use translation software, but if you don't know a little English, you may not pass the interview. The interviewer may adjust his English according to your level, mainly to see if you are inclined to emigrate.

You can't write or answer that you don't know anyone in America, but the relationship of the person you know should be answered skillfully. Don't let him think that you have defected to this friend. Those who are inclined to immigrate will not sign.
