eVisa
An electronically issued visa, applied for and received online.
Many destinations now offer eVisas for tourism and some medical travel. Processing is typically 3-7 days. Specific eligibility varies by passport.
What this means for you: confirm eVisa eligibility for your nationality and the specific visa category needed. Some treatments require traditional visa applications regardless.
What a term means for you depends on your own reports. Ask your treating doctor, or send your reports for a free review.
