Hello everyone!

My girlfriend and I (German and Austrian)

are planning to go to Thailand for around 6 months.

What are our best options to do this properly with Visa?

As far as I understood there are two options:

A) Enter the country as normal tourist, get a 30 day visa and then extend to 60 days. After that we have to leave the country and can come back with a new tourist visa? Is that correct? Or will we have to leave permanently once the 60 days are over and cannot come back.

B) Apply for a Multiple Entry Visa. Where exactly can I do that? Our flight is in 15 days already. Is that sufficient time?

Is it also possible to enter the country with a normal visa and then apply within the country for the multiple entry visa?

C) I assume there is also a way to go with Visa agencies. Is that recommended?

Many thanks in advance!
