Hello, does anyone know how long does it take in reality for a spouse of a Permanent Resident to obtain her GC? Would she get her advance parole and work authorization while she is awaiting her GC? She is already here on her student visa. What option would be better for them - file now while he is still a GC holder, file for his citizenship (he can already do it) and speed up the process by reporting that he became a US citizen? OR just wait until he gets his citizenship and then file for her? How long does it take to obtain citizenship from the time of filing? Lots of questions, I know...
Thanks for any answers...

Get citizenship first and then file I-130+I485 for spouse. I-485 cannot be approved without I-130 being approved, and the I-130 has to wait for a visa number to come up for a LPR filing, this can take YEARS. A US Citizen filing the I-130 will get an immediate visa number under the UN-Limited class.

Immediate Relatives of U.S. Citizens (IR): The spouse, widow(er) and unmarried children under 21 of a U.S. citizen, and the parent of a U.S. citizen who is 21 or older.

Family Second Preference (F2): Spouses, minor children, and unmarried sons and daughters (over age 20) of lawful permanent residents. (114,200) At least seventy-seven percent of all visas available for this category will go to the spouses and children; the remainder will be allocated to unmarried sons and daughters
