The Ministry of Foreign Affairs (www.mfa.go.th) oversees immigration and visas issues. Check the website or the nearest Thai embassy or consulate for application procedures and costs.
The Thai government allows tourist-visa exemptions for 41 different nationalities, including those from Australia, New Zealand, the USA and most of Europe, to enter the country without a prearranged visa.
For those arriving in the kingdom by air, a 30-day visa is issued without a fee. For those arriving via a land border, the arrival visa is 15 days.
Without proof of an onward ticket and suffcient funds for one’s projected stay any visitor can be denied entry, but in practice this is a formality that is rarely checked.
If you plan to stay in Thailand longer than 30 days (or 15 days for land arrivals), you should apply for the 60-day Tourist Visa from a Thai consulate or embassy before your trip. Contact the nearest Thai embassy or consulate to obtain application procedures and determine fees for tourist visas.
The Non-Immigrant Visa is good for 90 days and is intended for foreigners entering the country for business, study, retirement and extended family visits. There are multiple-entry visas available in this visa class; you’re more likely to be granted multiple entries if you apply at a Thai consulate in Europe, the US or Australia than elsewhere. If you plan to apply for a Thai work permit, you’ll need to possess a Non-Immigrant Visa ﬁrst.
