Which medical tests must I do before flying to Saudi Arabia?

You must pass a Wafid (GAMCA) medical test before your Saudi visa. Book online at wafid.com and pay the fee. The system assigns you an approved centre, so you cannot pick it. It checks chest X-ray for TB, plus blood and urine, and a physical exam. Your result must show FIT to get the visa. Results usually come in 2 to 5 days. Bring your passport and the appointment slip. If you are found UNFIT, you cannot travel, so do the test honestly and early. Keep the printed result safe.
