H4 EAD extension after H1B transfer approval

[sks0412]

HI,

My wife H4 EAD is valid for another year ,I recently got my H1B transfer approval ,H4 transfer was also filed with my H1B transfer only.

Now, Can I file for H4 EAD extension as well inspite if it being valid for more than 180 days ?

or I will have to wait and file its extension only 6 month prior to its expiry?
