student visa to spouse visa

I am married to a japanese national. I am still in language school with a few months left. Is it possible to convert from 'student' to 'spouse' residential status? If you have any experience on this, please share it will be a big help thanks.

Yes you can apply for change but the approval depends on your case I mean the documents and your spouse and everything.

There is nothing stopping you from applying for the new visa. I take it you already have your marriage registered with the Japanese government, is that right? You will need to get the necessary documents together to apply at your local immigration office.

Either of you need to prove that you have enough income to survive. There are conditions in order to get spouse visa.

You can apply for student visa to spouse visa but provide marriage certificate they can convert it but i think it will take some time.
