The continuous physical presence requirement for TPS eligibility is a requirement to make sure that you have been physically present in the United States since the designated date.
For example, the continuous physical presence date for Nepal is June 24, 2015. Therefore, an applicant for initial TPS registration must have been physically present inside the United States since June 24, 2015.
The law allows an exception to the continuous physical presence requirement for brief, casual and innocent departures from the United States. When you apply or re-register for TPS, you must inform USCIS of all absences from the United States since the continuous residence date. USCIS will determine whether the exception applies in your case.
Once you have been approved for TPS, use Form I-131, Application for Travel Document, to request advance parole. With Advance Parole, a TPS beneficiary can travel abroad.
Continuous physical presence is closely related to continuous residence for TPS.
