Planning a trip to Kenya for medical treatment or consultations requires proper travel authorization beforehand. You will need a valid passport scan, a recent digital photo, confirmed accommodation and flight bookings, plus a referral letter from your doctor or hospital in Kenya. The single entry eTA stays valid for 90 days and permits a stay of up to 90 days. I found the Kenya Medical eTA guide very clear about the application steps and document checklist. Processing times range from normal 3 to 5 days to super rush within 1 to 2 days, depending on your urgency. Just double check your nationality eligibility and make sure all your documents are clear before you submit the form. Also note that only US citizens can apply for the 5 year multiple entry option which is coming soon.
