If working in Gulf countries like Saudi Arabia, United Arab Emirates, Kuwait, Qatar, Bahrain, or Oman is on your mind, one of the steps that you cannot skip is your WAFID medical test. The treaty visa will be dependent on you undergoing a medical examination at an authorized WAFID medical center, as only then will you be cleared to the next step of the visa acquisition process. Process-wise, what it comes down to is that through this system, it will be confirmed that all consenting workers are healthy and medically fit before entering the GCC countries.
