Filing I130 for wife ( urgent question)

[CFY]

Hi,

I have applied for my citizen ship. I would like to apply for GC for my wife. Is it good to apply for I130 first or wait till I get my citizen ship.

She is already in her H1B. What are the forms she needs to file her I130 and wat the advantages of filing I130 asap?

thank you

[peace]

You cannot apply before you get your naturalization certificate.
