Applications for a health card can be completed at the general post office, or at a recognised health card office. Expats need only bring a copy of their passport with their residence visa, colour passport-sized photographs, and a completed application form, in addition to the basic fee. Renewals can now be done online at the Qatari government ePortal, or at a health card office.
