Looking for advice, for a friend.. He is 71 years old, has been here for 21 years, and currently has a non 'o" visa based on retirement. And need to know what he will need to show, in order to extend his visa for a year. ?

He has heard that, for people who have been in the country for over 20 years that they may only need to show 220,000B or an income from abroad of 20,000B per month.. but isn't sure whether this is true or not.

He has enquired about it at his local immigration, and they said at the time that they hadn't heard of it. So he may need written evidence to show them..

Any advice would be appreciated.

Thank you
