Visit back in Thailand every year just for 30 days normally however, virus has put a lid on that for a while.
Still have a query for when things get back to some form of normality.
Back in 2012 I had a dual entry Non-immigration-O visa issued and it was 90 days initially with a border run to pick up the last 90 days.
If I would have checked closer I could have had the normal 30 day entry on arrival and then used the 2 x 90 day later to get some more time there but..........anyhow
This allowed me to get a work permit if I needed one and to open a bank account.
