I am on 1 - B / I - 94 expiring on June 30th , 2013 . My current employer is filing for HB . To bridge the gap between June 30th and October 1st by getting an extended I - 94 , can I travel to Cancun by air on a weekend ? I entered US for the first time in Aug 2010 and have been here since then . This is my first US visa . I have more than 5 years of validity on my passport .
