I totally support AJ on this one.
One thing is you already have been practicing Modeling from past 2 years.
As far as I know you dont need a full time degree now only to hone your skills and get a job, by spending tens of thousands of dollars.
You can register for some short-time courses … like the ones they are offering here on CGSociety, click on the workshops button on top of this page.
If you are planning to move out of your country for better prospects, and if you believe that by getting a student visa and then after completing the course it will be easy to settle, you might be wrong, coz theres no guarantee about getting a job after your studies.
Better take some time…like 3 to 4 months… attend some online courses like the ones on CGSociety … u can check for other websites also …and then try to build a good demo reel with some help from your online teachers and give it try.
This is my opinion though, keeping in view that you already have been working on Modeling from past 2 years
