How many times can I apply for a 2-month tourist visa to Thailand each year?

Don't go to Phnom Penh for a tourist visa, notoriously difficult and may even give you one then put a void stamp on it, Laos, HCMC Vietnam or KL Malaysia is your best bet.

Elena please be prepared to show, if asked by Thai Immigration: 20,000 Thai baht or equivalent in CASH, your DEPARTURE ticket out of Thailand and your initial address where you will be staying.

Pardon me, but you state that in this year ...is that 2019?...you already have TWO 60 days tourist visas...Did you EXTEND those Tourist visas by 30 days each?

And now you are planning on getting another Tourist Visa and staying longer.

You may be successful in obtaining Tourist Visa once again, but upon entry back into Thailand , you may be asked by Thai Immigration : WHY do you stay so long in Thailand. Good Luck 🍀

okay there is no official rule on the number of tourist visas you can get from a thai consulate.

Each consulate has their own limit but seeing as you are not living here on back to back tourist visas you shouldn't have any problem getting a new one as long as you meet the requirements for the visa at the thai consulate where you're applying.
