Family-Based Green Cards

I want to know how I can come back to US. I came US 2006 like a guest, stayed about 5 years & left US. But my family still there, ex-wife, two daughters older 20 year old & younger 17. When my daughter turns 21 year old can she apply for family reunification, especially for me?

My US citizen father is filing an I-130 for me; will my husband automatically be accepted at the same time as me if I get accepted?

I am a US citizen turning 21 next month. Can I sponsor my dad to get a green card even if I am not holding his last name?

My wife got her green card in 2006 but since 2008 she has been staying continuously overseas. In 2009 she applied and received SB-1 visa but she was not able to return to US before it expired.In 2009 our daughter was born overseas. Just recently I have become a US citizen through the naturalization process. I am planning to bring all my family members to US in April 2012. What are our options?

My friend filed a petition for an adult child (over 21 years old) six years ago and just received notification this year that there's a visa number available for the child. Meanwhile, the child has traveled to study and obtained a permanent residence in Canada. However, the child still wants to join his mother to the United States. Will the US give the child a GC if all the requirements are met?

I just received my two year temporary green card, my malicious mother-in-law claims she went to immigration and put a "BLOCK" on me. Is this possible? Can she do this? I have a clean record good credit and have never been in trouble with the law. Should I be worried?

I am a US citizen, had applied for my parents GC in October 2009. Mom underwent fingerprinting three times here, but did not get her AOS done in time. End of last year my father (who got his EAD and AOS smoothly) had emergency heary bypass here, and then they had to leave back for India for more tests. Mom left on AP. Subsequently I wrote a letter to NBC, MO to ask them to expedite my mothers case. Yesterday I received a letter stating that she has go to Philadelphia USCIS office next week for "Completion of application to register for Perm residence." Mom is in India now.
