What are the best options for extending my stay in Thailand beyond 75 days?

I have heard from costumer service of Embassy that you cannot apply for Thai Visa if you’re located in Thailand itself. Well, it is indeed eVisa so I was wondering too if we cannot just try do it. If anyone did I’d like to know if that works!!

But I just found out you can go to Laos which isn’t really expensive from Bangkok, stay there for a day or two and apply there for the tourist visa. Thai embassy in Vientiane accepts all applies and what I have read from other people experience you will even got the visa the next day. On the site it states 2 working days (except on holidays) so I’m not sure. But spending 2 or 3 days in Vientiane doesn’t sound bad, can explore the city. I plan to expand my 45 days with +30 days and then do that and apply for just normal tourist visa to stay longer.

says you'd have to leave Thailand to activate assuming you're granted one so why not re-enter Visa exempt again (30 days) and extend or do you want to stay more than 135 days?

Your question doesn't makes sense because you use a Tourist visa to enter the country. Applying for it while you're here wouldn't help you at all.

But also you cannot get a tourist visa from Thailand, you have to get it before you come here.

If you enter visa except BEFORE April 1st you'll be stamped in for 45 days + 30 day extension as you said.

If you get a tourist visa before coming to Thailand you'll be stamped in for 60 days + 30 day extension. So getting the visa would give you 15 extra days.
