International students must maintain their F-1 non-immigrant status to remain in the U.S. with full-time enrollment status, to study at Sarah Lawrence. Undergraduate students must be enrolled in 12 credits per semester. Graduate students must be enrolled in 10 credits per semester. It is critical that students understand the importance of maintaining their F-1 visa so as to not violate international status.
The below webpage has been archived by USCIS, but still contains information related to the established guidelines as of August 2018: https://www.uscis.gov/news/news-releases/uscis-changing-policy-accrued-unlawful-presence-nonimmigrant-students-and-exchange-visitors
If an international student (holder of F-1 visa) has been out of the U.S. for more than five months, they need a new I-20 and possibly a new visa. Contact the appropriate DSO with enough time to process the required forms.
Below is general information on F-1 regulations, though these guidelines should not be taken as legal advice. The following list is not exhaustive and is subject to change. While Sarah Lawrence and International Student Services are available to assist students, maintaining F-1 status is the responsibility of the student.
