To Everyone who replied: from what I understand about her question, she is asking for the need of documents submission to the QATAR embassy in the Philippines and not on the Philippine embassy here in Doha. Yes indeed there is a need to submit documents such as passport, visa, and medical certificates for authentication purposes. Any type of visa issued by the government of Qatar (working, family, visit, business) will all be authenticated and verifed by their embassy in the Philippines. I hope this clears it up to your query.
