What visa options are available for a 3-6 month stay in Thailand without a return ticket?

If you plan to stay in Thailand for 3-6 months without a return ticket, you should consider several visa options. It's crucial to know the type of visa you need and the regulations that might apply upon arrival. You may require a Multi Entry Tourist Visa (METV) that allows multiple entries within 6 months, granting a 60-day stay per entry. Airlines may ask for a return ticket, so it's advised to either purchase a dummy ticket online to meet airline requirements or be ready to explain your travel plans to immigration upon arrival.
