I have been living in Thailand now for 3 years. I have been working at the same job since August 2021 and just renewed again for another year. My income is only 33,666 as I am a teacher. I would love to travel but need to apply for a credit card to secure bookings. Are there any options for me here that would be halfway successful to try? Yes I do hold a work permit and Non-B visa. Currently my job pays through KTB but I know their requirements are strict. Any help would be great!
