I am a US Citizen, I recently filed an I-130 for my foreign spouse at the Chicago Lockbox, we are both living in Spain together. We received notice that our case was sent to the California Service Center. I feel confident we will be approved and have the I-130 sent to the NVC eventually, but I want to know if there is anything I can prepare in the mean time so we can expedite the return of any solicited documents or information. What will the NVC ask for after the USCIS approves the case? Can I start preparing anything now? Will we need to send the same documentation required by the I-130 to demonstrate the bonafides of our marriage? Thanks!
