International conventions regard travels shorter than 3 month as tourist, longer is more doubtful, if can be classified as tourist.

Remember that Immigration Officers may work long hours 6 days a week, and have less than 14 days holiday every year, so can be hard to understand that other people have several months of holiday, and not appear to be a wealthy person by apperance.

For the ED-visa you have to actually study, and to attend classes, and not be travelling.

More likely to be 2 visaruns back to back, that lead to the restriction.

All Immigration officers are allowed to ask all the questions they like, without it being “suspecious”.

When entering visa excempt of tourist visa there is a requirement to be able to show that you intent to leave Thailand within the granted period, so also nothing odious about that neither.

Some tourist often misunderstand a onward ticket as to be a returnticket.

Every country has their own "templates" to make documents, That's why it is a advantage to apply in your homecountry.

Then you also save money by not needing a ticket to a 3. country and the stay there for the whole period from applicating until the visa is granted ( or rejected, without any refund of the visafee)

Copying other persons document styles, may backfire.

Depends on Embassy, if the Embassy asks for it, the you have to supply it.

That’s one of the reasons that makes it best to apply in your homecountry.

Why don’t you read all the great posts in the group, that is how to learn about the requirements, and how other people have solved those questions.

When you posts as anonymous, you must do the work yourself, since you don’t contribute to the group.

Nobody gets a reason why, a application is rejected.

Read the website of the Embassy to apply at.

You have obviously not read the Embassy website thoroughly enough, then you wouldn’t ask that questly.

Search the group for the posts, specifical for the Embassy, you want to apply at, then you will find the relevant answers.

There are dates on all posts so easy to see the most recent.

The Thai Embassy website also have important information.
