What visa should I enter Thailand on for marrying my girlfriend, and can I do it with a one-way ticket?

So, for your question #1: You don't have to have a visa when you enter Thailand (I assume you're US, UK, or AU). An agent can set it up for you to get a Non-O after you're here (at least they were able to in my case). ~ EDIT: I just remembered the recent news that the initial stay period for visa-exempt entry got reduced from 60 days to 30 days, so that could make this method trickier, but an agent could probably straighten it out.

Question #2: You can come on a one-way ticket, but the rule is that you need to have an onward ticket to show when you arrive in Thailand (some say you might even be asked to show that by airport staff while you're still in your home country, but I don't think that happens but very rarely). In reality, folks are almost never made by Thai Immigration to show that onward ticket (I wasn't, and other people I know weren't)—but you need to be prepared in case you're that 0.1% case who gets asked. Easiest thing to do would be to buy a cheap ticket to a nearby country that lets you do visa-exempt arrival like Cambodia (I mean before you fly to Thailand, so you'll have it on you as you're entering). It will be something like $60-$70. If you hate to waste the money, you could actually use the ticket, but then you'd have the extra expense of that trip, including a re-entry permit for getting back into Thailand.

Another rule is the one saying you need to be able to show 20,000 THB (or your home currency equivalent) upon entry. Again with this one, I've never heard of anyone being made to show this, but of course you want to have it on you just in case. And you probably would anyway, coming to Thailand with the intention of living here. They want to see it in cash, presumably because that's the only quick way they could verify it while you have 100 people standing in line behind you.

As others said. Get a NonO from the visa site. Retirement if you can, otherwise marriage.

For retirement you need to be 50+ and best have 800k to spare. Enter the country, open account, deposit the 800k (make sure that the bank can identify it as foreign money!), and do the extension near the end of your 90 day visa. You can do it with 65k per month but ask your immigration for that just after arriving!

Otherwise: marriage visa where you need only 400k in the bank.

If you have the money, go for elite visa or LTR, but that’s on another level.

Just don’t enter on visa exempt because you can’t open an account as a tourist.

The plane ticket shouldn’t be a problem..get a cheap onward ticket if you want…regarding the visa definitely visit an Agent they will help you through the process

Thai Consulate in Los Angeles would not issue me a Non O visa without a return ticket. This was the Consulate not the airlines policy.

Bought a cheap one way to Vietnam and all was fine

Enter on a tourist visa and apply for Non Immigrant O visa when you're here.

Have a look at

For a few dollars you can book an onward flight and show a ticket at check-in. Simple

If you apply non-o based on marriage visa before you go Thailand then no problem with airlines but if you come on tourist visa or visa extempt then expect you need return flight or onward ticket depends on your airline.

I only book one way .because it's cheaper booking return in thailand

Apply for a non o visa from your country,

You can state that your intention are to get a retierment if you over 50 years old

If under… state it is to gett s marige visa

(If your girlfriend still avis le when you come back to Thailand,

Maybe she found a man with more mony..

With the 60 days visa the d ont aske enimore for the retour tiket, at liste from europe, i come whit one way and all god

I entered the country in February on a tourist visa , then whilst here , went online to Thaievisa and converted to a non immigration type o visa , which can then be converted to a marriage visa .

I arrived on a one way ticket also from the uk and everyone from to check-in staff too immigration did not ask me any question or want proof of a return ticket.

Hope this helps

Get a No -O based on being over 50 then no matter what happens your extension will be ok

Go to the temple n give the monk some money n food take a video n show proof of your loyalty to thailand n they will welcome n accept u

Go to onwardticket.com you can purchase a flight to Laos for 12.00 usd. I have done this many times just in case but I have never been asked when I only have a one way ticket to Thailand. Better safe than sorry. I now have a multiple entry retirement visa, soon to be switched to a marriage visa.

You can also have an agent get you a bank account for about 5000 baht on a tourist exempt.

If you can afford the 800k, better use regular Non-O.

Marriage Visa can be pita, especially the yearly extensions.

I'd suggest you have a better chance of not requiring a return flight if you come with a tourist visa rather than visa exempt but check with your airline. As to getting married you have some hoops to jump through such as getting a "freedom to marry" certificate from your embassy in Thailand which can take time and I believe some immigration offices require you to have been married for at least 2 months before they will allow you to apply for a Non-O visa based on marriage

To obtain an extension of stay based on marriage you need to have a Thai bank account. To open a bank account you need a long term visa (You cannt open a bank account on a tourist visa or visa exempt), Be aware that while an marriage extension requires 400,000 thb in your bank and a Retirment extension (for those over 50 years) needs 800,00 thb in the bank, that a retirement extension is much easier as it requires you to jump through ,amy less hoops.

A lot would depend on your passport country. Your name suggests that you are probably from one of the 93 countries than can enter visa exempt and get a stamp for 60 days.

With at least 15 days left on a valid stamp (some offices 21) you can convert to a in country Non O based on marriage but it will depend on your marriage date. Having a girlfriend won’t get you that visa.

A one way ticket will be up to your airlines policy. Some will insist on a ticket out within the number of days your entry scheme allows, regardless that you could get an extension or change to another visa type. Some don’t seem to care.
