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?
One of the ways could be for your daughter to apply for your green card when she turns 21. The problem is, if you were unlawfully present in USA for more than a year, you may be barred from entering USA for 10 years.
