Iam a LPR currently residing in the US and will be applying for F2A for my wife who currently lives outside the US. I understand that I have to use form I-130. Would I also need to complete form I-864 and/or G-325A ? If so at what point during the application would I need to send in these additional documents i.e I-864 and G-325A ? It it during the application i.e along with I-130 or is it during consular processing ?
