The population registrar department handles all issues concerning population registry (residence and status in Judea and Samaria), entry and departure from the region, visiting licenses and entrance for foreigners, entry permits to Israel for various matters (medical, legal, family unification, prisoner visitations etc.), seam zones, movement between Gaza and Judea and Samaria and more. The department's officers deal with thousands of applications and hundreds of petitions to the Supreme Court on administrative matters, thereby being involved in the advancement of their field.

The entrance of foreign citizens into Judea and Samaria is dealt with by foreign entry regulations, consolidated in conjunction with the interior and foreign ministries. The regulations determine categories, and those who fall within them may submit a request for entry into Judea and Samaria, (by means of category 2/B approval). By virtue of visa limitations, the maximal period is 3 months, and it is possible to extend it under appropriate circumstances, in accordance with policy and the security situation. In the matter of submitting requests and the criteria of approval, regulations distinguish between citizens of states which are signatory to the visa exemption agreement and those which are not.
