Here's my situation:
I am a U.S. citizen, and my wife and son are Japanese nationals.
We married in the U.S., and they are now back in Japan and I will join then in June.
I will start the immigration process, but my question is,
Since America and Japan have the Visa waiver program, and we are married,
do I still need spouse Visa?
Also, what is the process for immigration?
Is there a benefit for citizenship over permanent resident?
