Im in my first year at university in Thailand. I currently have a non-immigrant "ED" multiple entry visa which requires me to go to immigration every 3 months to get another stamp. My query is once my visa is due to expire, am I able to renew the visa within Thailand as I will be at university for the next 4 years. Cheers in advance

When you make extensions at immigration you are not extending your visa you are extending your permit to stay.

The experation of your visa means nothing after you are in Thailand.

You can keep getting extensions as long as you qualify each time.

Thank you

The university should be able to help you with the necessary paper work.
