The USCIS Final Rule that goes into effect on January 17, 2017 allows for a:
10 day grace period before the status begins and after the status ends.
Up to 60 day grace period based on cessation of the employment.
(l) Period of stay. (1) An alien admissible in E-1, E-2, E-3, H-1B, L-1, or TN classification and his or her dependents may be admitted to the United States or otherwise provided such status for the validity period of the petition, or for a validity period otherwise authorized for the E-1, E-2, E-3, and TN classifications, plus an additional period of up to 10 days before the validity period begins and 10 days after the validity period ends. Unless authorized under 8 CFR 274a.12, the alien may not work except during the validity period.
(2) An alien admitted or otherwise provided status in E-1, E-2, E-3, H-1B, H-1B1, L-1, O-1 or TN classification and his or her dependents shall not be considered to have failed to maintain nonimmigrant status solely on the basis of a cessation of the employment on which the alien’s classification was based, for up to 60 consecutive days or until the end of the authorized validity period, whichever is shorter, once during each authorized validity period. DHS may eliminate or shorten this 60-day period as a matter of discretion. Unless otherwise authorized under 8 CFR 274a.12, the alien may not work during such a period.
(3) An alien in any authorized period described in paragraph (l) of this section may apply for and be granted an extension of stay under paragraph (c)(4) of this section or change of status under 8 CFR 248.1, if otherwise eligible.
