Do I need to show a ticket back home when entering Thailand on a one-way ticket?

When entering Thailand with a one-way ticket, tourists may be asked for proof of onward travel within 60 days of arrival, but this largely depends on immigration practices and the airline's requirements. Some travelers report that immigration rarely checks for exit tickets, although airlines might request them. It is advisable to check with your airline and consider purchasing a low-cost train ticket to a neighboring country for peace of mind. Visa type may also affect whether an onward ticket is required, especially for those traveling under tourist visas or when applying for longer stays.
