Can I sponsor my adult son with Autism on a Non O Retirement Visa in Thailand?

You can not sponsor anyone with an Non O Retirement visa. If your son is less than. 20 years old, you can sponsor him with a Non O-A Retirement visa from your home country, but if he is over 20 then you will need to get an agent to see if he qualifies for a medical exemption, which are issued on a case by case basis. You will need to show ample passive income to cover both of your expenses, plus insurance, etc. Thai insurance companies are very expensive and very shadey and don't like to cover pre existing conditions, so you may end up paying a lot for his care. Unfortunately this system isnt set up for anyone with special needs.

I tried to send you a private message on messenger, but it is blocking me

He will need his own visa. And resources. They need to be sure he won’t be a financial liability, autistic or not.

My daughter is also on the spectrum (AuDhd).. and the requirements aren’t any different. You can sponsor a legally married spouse.. they still need to qualify and have their own visa and requirements.

Have you guys been here before ?

Horrible idea, honestly

Ypu cannot sponsor him. But, perhaps the least costly and easiest visa for him would be the DTV. Soft power medical would likely work out easily for him. But you would need to co-ordinate his care with an accredited facility in Thailand and have a physician provide a 6-12 month treatment plan. His bank account would need to reflect the 500k baht balance in his name only.

Your son is an adult, he will need to find his own visa. Not easy in the circumstances so a Thai Privilege visa may be the best option although relatively expensive
