during my entry the inspector at the port of entry while tearing the i-94 from main page ,tore some of my numbers.since that was my 1st time entry i didnt speak anything and neither that guy gave that torn apart part attached to the main i-94.later on i contacted the customs and border security(cbs) and told them my problem.after some questions to verify my authenticity,the guy on phone gave me my i-94 number.now i have noted my number. but my concern is does it cause problem in future becos some number are missing becos of tearing?i can tell them my full i-94 number. i m thinking of extending my stay.and i will be sending my i-94 for that purpose ......will it cause any hassles or delay becos of i-94 missing numbers? pls suggest
