Can a Green Card holder parent petition?

[dizizit]

Hello

My mom is a green card holder, can she petition my sister who is single and over 21 years old? How long does it usually take?

Or just wait for my mom to be a US citizen then she can petition my sister?

Which one is easier and faster?

That's FB2B, and it takes several years.

Or just wait for my mom to be a US citizen then she can petition my sister?

That would be FB1, but there's no point in waiting. File the I-130 now.

Is your sister inside or outside the US? If inside, legally or illegally? Those factors affect the length of her wait.

if your sister is outside the US she can be petitioned as long as she is unmarried.
