Do you mean getting endorsed in Singapore or Thailand? Is it for Thai work permit? If yes you can go to any private hospital in Thailand and tell them you need a medical certificate for work permit purposes.
So, if the work Permit is to be renewed in December, we must have 4 Thais in the Social Security record for August - November. The labour department wouldn't look back at the number of employed Thais for the months before?
thank you. So if January the company pays Social Security for 3 Thais , and February to December the company pays Social Security for 4 Thais, the Work Permit cannot be renewed?
