EAD Question

[precious123]

Dear Attorney,

Below are my details:

Current work status : H1B
Applied for I-485 , July'07 filer, priority date: jun-2006, EB3 category

My husband details:

Current work status : H1B
Applied for I-485 , July'07 filer, priority date: Feb-2005, EB3 category

We both have separate EADs and H1B visas and are independent of each other currently.

Because my priority date is 2006 and my husband's is in 2005, there is more possibility that he may get GC before my PD becomes current.
When my husband's priority date becomes current, he wants to file it for me again so i would get GC along with him.

I am now considering to look out for jobs and use my EAD card with new employer.

Can I make my EAD active ? Will it cause any problems when my husband's priority date becomes current and when we file my application along with his ?

Any input is greatly appreciated.

Thanks.
