I want to apply B-2 extension for my parents. When filling I-539 Form, I found out that there was only the printed number on their I-94 cards, which is a random number. These numbers definitely are not their 1st I-94 numbers. Just wonder if this is normal for B-2. From my own experience, I know for certain that it is untrue for F-1.
Since we do not have a record of their 1st I-94 numbers, where I could get those if they were needed.
Thanks.
