There is no such thing as an international TESOL certificate - it's just a word the course providers use. However, if your current certificate is issued by a well known TESOL course provider, you should have no problem in getting it accepted worldwide.
Even better would be a certificate issued by a state authority. A state teacher licence would be excellent, but some countries may require a certified translation of it for visa and/or work permit applications.
I offer any information or advice 'as is' and hope that it has been of help. I am not an admin of this board, and my postings do not necessarily reflect the opinions of the board management.
