If your GAMCA medical certificate expires before your visa process is complete, you will almost certainly need to undergo a new medical examination.
Given how brief these certificates' validity periods are, this is a typical scenario. Here's what you should do:
A GAMCA/WAFID medical fit report is typically valid for 60 to 90 days (2 to 3 months) from the date of issuance. The exact duration can vary slightly, and some sources mention 60 days, while others mention 90 days. Always check the specific validity period mentioned on your certificate or as per the latest guidelines for your destination country.
This short validity period is because GCC countries require your health information to be current for visa applications and to prevent the spread of communicable diseases.
Immediately notify your prospective employer or sponsor in the GCC country about the expired certificate. They may be able to advise you on the next steps and any specific requirements from their end.
Since you've been through it once, you'll know what to expect. Ensure you are in good health, and if there were any minor issues in your previous report, try to address them before the retest.
Once you receive your new "Fit" medical certificate, prioritize submitting all necessary documents for your visa application as quickly as possible to avoid another expiry.
While it can be frustrating to repeat the process, it's a mandatory step to ensure compliance with the health regulations of the GCC countries.
