2月底被lay off (H-1B在2009年expire), 但是在1月份已经找到新的公司，并且新公司已经在2月初申请了新的H-1B，现已经收到新的receipt ( 但是starting date是6月1日)。问题是被lay off( 2月底)到新的上班时间(6月1日)中间会不会有Gap的问题？新公司的律师说没有关系。他引用了H-1B portability rules: "a person in H-1B status may commence new employment upon the filing of new petition by the prospective employer if: (1) s/he was lawfully admitted; (2) the new petition is nonfrivolous; (3) the new petition was filed before the date of expiration of the period of stay authorized by the AG of the H-1B beneficiary; and (4) subsequent to such lawful admission the H-1B beneficiary has not been employed without authorization before the filing of such petition."公司的律师对吗？谢谢！
