在I539中,Part2里问题1和问题2应该是2选一，延期的话应该是选问题1。但是在USCIS
官网上有如下要求
Complete all sections of the form. We will reject the form if these fields
are missing:
Part 1 – Information About You
Family Name
Mailing Address
Date of Birth
Part 2 – Application Type
Number 2.a.
Number of People Included in This Application.
是说part2 的2.a.必须要填
请问这里怎么填？谢谢！
