Family-Based Green Cards

I am currently in the US on a h1b visa. My I-140 has been approved under eb3 category but looks like it will really take a while for the visa numbers to be current. My brother is a naturalized citizen. Can he file for my green card under family based siblings category? I was told by someone that i cannot file 2 immigrant petitions. Is that true?

My mother is an american born in US and I, her daughter was born in Mexico. Am I an American citizen or what papers do I need and what do I need to do? Do I need a green card or what should I do? I have 4 sons that were born in US ages 22,20,15,12. Can one of them sponsor me or what status to be a permanent resident.

I am a US Citizen through naturalization. I have applied for GC for both my parents and they are here. I applied I130 and I485 concurrently. I recd the notice letters and my parents got thier finger printing done on 03/22/2010. My Mother's I-94 is expiring on May 25, 2010. Do I need to apply for an I-94 extension since their 485 is still pending or can she stay till GC is approved without a new I-94 extenstion. Both my parents have a 10 year valid B2 visa till 2016. Please advise if I need to apply for a I-94 visa extension.

I am a citizen here and would like to apply GC for my brother's family in India. My question is brother and family have 10 yr visiting visa and they keep travelling here every 2 yrs. Once I apply for their green card, can they still continue to visit here with their visitor visa? When would their visitor visa gets invalid.

My sister just got her green card last year. Can she petition her siblings ages 22 and 24? how long does the processing take?

My parents got GC and I could not get it since I was 21. I am now in the US on H-1B. My mom applied for me when she was a permanent resident under the unmarried son/daughter category. In 2009 I got a letter from USCIS that my visa is available since my priority date was Sept 2001 but in 2009 I was already married and my mom became a citizen after we got married. My question is - can I file for new I-130 and request them to allow me to use the old priority date (Sept 2001)? What are the chances of them allowing me to do that?

I am a U.S citizen and I want to apply GC for my mother. She has a multiple visa for U.S. If she comes here and then I apply for her do they need a medical for her in here or not?

I came on an F1 visa but dropped out due to financial difficulties, I have been working without a work permit, my husband who is a US citizen,has been unemployed for the last two years due to a car accident,so we had to use my income for the I-864 now they USCIS want me to verify my employment eligibility, how can we deal with this problem?

I filled the petition for my son when I was GC holder.My son got married 10 days before I got citizenship.Now his petition is denied.USCIS want me to file I-130 again. Please tell me I have to file I-130 or there is any other way.

I got my green card back in 2003, I traveled to the U.S. in search of a better life. Since my grandmother was sick I had to comeback to my home country in 2008. I've been out of the U.S. for more than a year. My grandmother is fine now and I'd like to comeback to the U.S. My green card expires in 2014, so it's still valid now. Will I be allowed to comeback to the U.S.?
