Hi
My spouse is a green card holder. I want to get a student visa. Is it possible to get it ? Will they think my intention is to immigrate..the fact is I don't want to permanently immigrate I want to only study. Is it possible to get a student visa ?

You will face a lot of difficulty because as a student applicant you will have to convince a consular officer that you would depart the US after your studies....yet you want to study now, presumably in the same town where your spouse lives...and why would you go back home to country (x)? This will be tough.

Actually my spouse too will at that point move back as soon as I am done with my studies (we want to reside back home once I am done with my education)..Will this help if my spouse tells the embassy regarding his desire to move back once I am done with my education ?

The rules are changing a lot on F-1 and you need to get the visa at your country of origin.My best guess is you will have a hard time convincing the consulate on your case moreso with your intent and that of your spouse to go back with you which is not her "proper" place as a LPR.
