* How many types of Entry ?
Entry types :
When applying for a visa, it is also important to consider whether you will leave and re-enter Thailand during your stay.
@ There are three entry options for a non-immigrant Visa:
1) Single Entry (all visa types): This visa is valid for 3 months from the date of issue. It allows you to enter Thailand for a single period of up to 90 days, after which you must leave the country. If you wish to stay longer, you will require a new visa for which you will have to apply for, outside of Thailand (visa run). However, it is possible to extend the single entry visa for 30 days without leaving the country by applying for an extension at the Immigration Office.
2) Multiple Entry (O, B and ED visa): Visas for work, studies, retirement and family unifications are valid for 12 months from the date of issue. They allow you to enter Thailand as many times as you wish for stays of up to 90 days. It is always better to get a multiple-entry visa so you will not have to visit a consulate for a new visa every three months. Be aware that the consulate will often try to encourage you to get a single- entry Visa and may even tell you that they do not issue multiple-entry visas. However, when dealing with the Thai bureaucracy, stay patient and friendly to ensure you get what you are looking for.
3) Three Year Multiple Entry (B visa only): The three year multiple entry visa is valid for 36 months from the date of issue. It allows you to enter Thailand as many times as you like, as long as your individual stays do not exceed 90 days.
