How to update my I94 ?


In Oct 2016, I got my H4 extension approved until March, 2020 along with my spouse (H1b extension). My current visa is expiring on 20th March 2017. I travel to India in Nov, 2016 and came back in Dec,2016 without new Visa stamping.

At port of entry, Immigration officer entered my I-94 expire date as 30 March,2017.

Does it mean I need to leave country before 30th March,2017 ?

Is their any way to update I-94 without traveling out of the country?

Can we file I-539 extension of stay or Should I visit to CBP office to update I-94?

Thanks in advance for reply.

Appreciate your help.
