I have to file for H1B extension and also H4 concurrently. My H1B expires in Jan 2019. My daughter's passport expires on Dec 2018. So I got her passport renewed. The H4 extension form (i539) has sections which asks about the i94 details and i believe i have to mention the old passport details as its that passport on the i94 record. My question is where to mention new passport details? or should I put new passport details in the i94 details section (which doesn't seem correct).
