'Do I need a visa to visit Thailand' is one of the most commonly asked questions. And it's easy to understand why. Thailand’s visa rules can seem a little confusing and are constantly changing, but hopefully this will shed some light on the situation.

There are two fundamental visa options for a visitor to Thailand from most countries -:

1. Arrive without a visa and get a free 30 day entry stamp on arrival, which can later be extended by up to 10 days at an immigration post in Thailand.

2. Apply to a Thai consulate for a visa before you travel. Details on types of visa and how to apply for them are given below.

Important change: Visa Runs
It used to be that you could arrive in Thailand with no proof of onward travel, be granted a free 30-day entry stamp, and extend your stay indefinitely by popping over the border and back every month to renew your entry stamp. This is no longer the case. You are still able to do up to two visa runs, extending your stay up to a maximum of 90 days, but the next time you leave the country you will not be permitted to return for a further 90 days.

Important warning
Do not overstay your visa in Thailand, even by a few hours. If you want to stay longer, get the visa extended or do a visa run before your visa expires.

Some travelers may tell you that overstaying your visa by a few days isn’t a problem and that you’ll just have to pay a fine of 500 baht a day. While it is true that you will just be fined if you turn up at the airport or border with an expired visa, if you are discovered with an out-of-date visa in any other circumstances you will be arrested and detained at the Immigration Detention Centre - an exceptionally grim place which Amnesty International has been campaigning to have closed for a long time.
