where can can i find the I-94 number on the visa?

The I-94 number is not on the visa. It is given to a person upon arrival in the US by Customs and Border Protection. You can access the number along with your entry record by going to https//94.cbp.dhs.gov.if you entered in May 2013 and later in any legal manner other than by land. Prior to that time, physical I-94 cards were given to all legal nonimmigrant entrants to the US with the numbers on the cards.   Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
