General Green Card

My brother got US Citizenship this month. I would like to apply Green Card using my brother's citizenship.Is it possible ? How long it will take . Now I am holding H1B.

Q1. Can a legal permanent resident(LPR) change career after say one year from his AOS approval to an entirely different field from the one for which his labor and his AOS was approved? Will this raise any red flags at the time of citizenship?

Q2. In other words, after receiving green card on the basis of say job in computer industry, when can one change his/her profession to an entirely different field (let say opening up a restaurant or go into real estate on full time basis) without jeopardizing the citizenship? Would waiting for one year(or some other amount of time?) after AOS approval be good enough to satisfy the "intent to work for in the field noted in labor application on a permanent basis"?

Q3. Is the person after receiving green card on the basis of employment in certain field stuck in that field for ever?

Q4. What are you thoughts in general about this scenario and how should one go about it?

I have consulted the local lawyers here but they have failed to answer this question with conviction. Can two Labor applications be filed for me by two companies (current and future employers) at the same time ?

I had accepted an offer of employment from a well established Indian Consultancy company last year in the month of June 2007. I was given the pre approved labor and they filed I 140 and 485, EAD, AP during that Visa bulletin fiasco last year. I got EAD and AP for both me and for my wife. My I 140 approved from TSC last month. Now I have a better opportunity.
My employer is threatening to withdraw GC files processing unless I work with them till I get my GC.

Qo1. Is that possible for them to withdraw like that?

Qo2. Does that affect my GC process in negative way?

Qo3. What I have to do in case they withdraw?

Qo4. Is it possible to re-start the whole GC process again in case?

Qo5. By the time I file AC 21, if the present employer withdraws the GC files, what happens to my case?

Qo6. How do we know whether they have withdrawn GC process or not?

Q1. How soon can I leave my petitioning employer once I get my green card approval?

Q2. I did not willingly left the GC sponsor employer but actually after three months I got my GC, i got laid off from the project and due to the bad economy , my employer was not able to get me other project so he gave me letter saying that he wont be able to pay me salary since he doesnt have any project for me.And, after getting that letter I resigned from GC sponsor employer.

Q3. I am employed at the XYZ University (XYZU). I applied for 485 myself (without attorney). My 485 was approved last month and I got my passport stamped in July. My contract with XYZU is coming to an end. My job is renewed every year based on the availability of funding. I have been with XYZU for the last 5 years. There is a possibility that they (XYZU) may not extend the contract because the research grant I got is coming to an end in september.
Will my termination from the job at XYZU affect my Green Card in the future, and is it better to be terminated from service (based on unavailability of funding) by the WVU or is it better to offer my resignation?

Should H-1 be renewed while the AOS is pending?

Rajiv, this month’s visa bulletin shows our category is current. What does this mean for people who have already applied for 485. Have AP and EAD. And now their dates are current again? Does it mean they will get a GC via mail? What if I haven’t had my FP done yet?

I have applied for 485 as the primary applicant and my wife is the secondary applicant. Right now both of us are on H1 visa. We had applied for EAD and AP and intend to apply for renewal soon as we near 120 days.
I am on my 7th year of H1 and my wife is on 2nd year of H1 and 3 year of (H1 and H4 combine). Her current H1 expires on April 2010.
I intend to remain on H1 itself and have no intentions of using my EAD.
Can you please clarify these questions.

My friend lost his job on Friday when he was working on EAD (this is not the employer who has applied for GC). His i-140 was approved last year in May. He is looking for new job which would take couple of weeks. I have following question for the situation:
