EAD

I am currently on my H1B extension and my employer filed a petition,I-140 under EB3 category which was approved. I cannot file for an adjustment of status at the moment so if my H1 B visa expires before I can file for the AOS in that case does my employer have to file for an extension for H1b or is it the EAD. I am confused if they are two diffrent things or one and the same. Please advise.

I am employed with H1-B and EAD. My wife has EAD through my petition. She is looking into working as an Independent Consultant (Self Employed). Is she allowed to be IC under EAD?

My 485 is pending and I am on advance parole and EAD, my employment based GC priority date date was June 2006. I want to be an investor in my friends start up company. I wont be leaving my current job but only investing in it. Should that be an issue If I dont have my GC?

I am currently a PhD student and preparing for application for OPT. Previously in 2004 upon earning BS degree, I got OPT and worked for a summer. In preparation for a new OPT, I realized that I need to provide copy of front and back of the previous EAD card. However, I cannot find the card. I just found copy of I-765, I-94, and I-20 for the previous OPT.If I submit without copy of the previous EAD card, will I be likely to be denied for the new OPT?
Also, what is the safest way to deal with this situation.

I have EAD/Pending AOS. I ported to employer B based on AC21 in 2008.
Now i am considering a great opportunity:
-Joining S corporation in Florida
_I will receive similar hourly rate as prior employer
-similar job
-i will receive 40% of profits on top of salary
-the new corporation will be my fututre full time job
Does the new corporation have to be huge with lot of finances for me to use the AC21?
I have valid EAD can I join as a partner in the S corporation in Florida?
Any thoughts things i,ve to carefull with?

Below are the validity dates of my L2 Visa,I-94& EAD:

L2 Visa Expiration Date: 18JUL2010
I-94 : 06MAY2011
EAD expiration date: 02OCT2010
I would like to apply for EAD renewal on June 4th, 2010 [120 days before EAD expiration]
Since I & my husband have I-94 valid till May 2011, my husband's company is planning to extend L1/L2 visas next year. Will my EAD renewal process have an impact with L2validity? As per my understanding, since I would remain on valid L2 visa after 18 July,2010 for 7 months[till I-94 expiration] can I renew my EAD without necessarily extending my L2visa.

My husband's employer are busy with a L1 / L2 application for our family. My husband will go to the US (in June) on his L1 visa, 2 months before me and the children, since I have to wait for them to finish their school year in July. We will join him end of July. When he goes over in June ... Can he
1) apply for my SS number
2) hand in the forms for my EAD
without me being in the country, or does that have to wait till August when I arrive?
