Till when can I apply for an H4 ead?

My husband received his approved I 140 today. I am presently in India. I am reaching US on 21st December. Will I still have time to apply for EAD after 21st Dec 2015 this year? I do not want to wait till next year.

H-4 EAD can be applied anytime after you return to US. So it can be filed in Dec 2015, Jan 2016 or even later.

If you have all the paperwork ready, it can be filed as early as Dec 21, 2015.
