I am a US citizen and I need to petition for my mother to come to US. What documents do I need to supply?

I agree with my colleague, 9-18 months, depending on her country. You start things with the I-130 ... read the instructions for additional forms and documents that are required. Confusing? Consider paying an attorney for a consultation. Many of us use Skype.

Depending on her country of origin, it will probably take 9-18 months. You will need your birth certificate, proof of US citizenship and her passport for starters.

You should submit proof of your US citizenship and your birth certificate. The process will probably take between 8 and 12 months. Please see
