However, the law specifies that one reason for OFPRA to process an asylum claim in Accelerated Procedure is that “without legitimate reason, the applicant who irregularly entered French territory or remained there irregularly did not introduce their asylum claim in a period of 90 days as from the date they has entered the French territory.”[1] Prior to the 2018 reform, this time limit was 120 days.
I would interpret that as meaning - If they haven't registered within the 90/120 days, that they would then no longer be eligible able to register. If not registered, then they are illegals, and thus liable for arrest.
