In addition to above may also be asked to show proof of funds I believe it is 20,000 baht which can be equivalent in other currency

Visa exempt 30 days can extend 30 days once in Thailand ...assuming you are a US citizen looking to travel to Thailand

North of Chiang Rai loved this place stayed in cottage with private small plunge pool

Suggest going to Chiang Rai as well. Cheap bus ride if I remember correctly about 3 hours. Nice roads to explore around there as well.

Are you at least 50 years old?

Regardless over 50 requires own retirement extension/money in bank. Under 50 dependent still requires this after turning 50.

Some Canadian banks Wise can not be set up as payee. You also don't want the bank in Canada to convert to baht as you will get a poor exchange rate. Wire transfers in Canadian funds often require to do in person at Canadian bank. Also have met Canadians here that bank in Canada is saying they will have to close account due to not living in country/several transfers of $$$ out of the country. Just some things to watch for.

You can just arrive visa exempt again
