<human>: Can you summarize the given text in a few sentences?

I am an American (25f) living in Japan, and I started dating a Japanese guy (26m) about six months ago.  I normally would not start thinking about marriage this early, but I want to go back to the U.S. later this year.  We are in love and have both started saying that we want to be together forever.  He wants to follow me to the U.S. and wants to start looking for jobs so that he can get a work visa.  Our backup plan, if he can't find work, is for him to go on a tourist visa, find a job once he's there, and change his visa at that point.  

I just can't help but notice how much easier it would be for him to live in the U.S. if we just got married.  I'm totally committed to him and would be really happy to get married.  I have been in much longer relationships and never felt this sure about anyone before.  He hasn't brought up the idea, though.  Should I?  Or is it too soon, and we should just stick with the original plan?  Thanks in advance for any and all advice.
<bot>: I want to get married after only six months because I am in an international relationship and want to go back to my home country soon.  Is it too early, or the best way to go in our situation?
