As you can see, there are many reasons why foreigners like to live in Thailand and Thai language is one of the key factors. Even though, many Thais can speak English fluently but not everyone can. It is very difficult for foreigners to communicate with the local people that unable to speak English. Therefore, studying Thai language will make lives much easier and more comfortable for those foreigners who plan to live and do business in Thailand. Moreover, I believe that Thai language can be easy for foreigners if they study from basic level to advance level and speak it more frequently. In my opinion, it is not necessary to learn Thai language but it will be beneficial the foreigners if they know how to speak Thai.
