If you are approached by an immigration official inside the U.S.

(tl;dr: Do not open doors; remain silent; do not sign anything; report it and record it; retain an attorney.)

Call your university’s offices and/or email the Refugee Rights Project’s airport hotline email. The hotline can refer you to a lawyer currently working at the airport where you arrived.
