-Received my CC letter on the 27, Sept,2019

does anyone know how long its take for NVC to send an interview letter after case complete? Or someone who could share experienced please

Thank you

My friend and her husband are living with us. She is trying to file her papers so she can go to school next year. She was adopted (not legally, basically just given) by an aunt in the states from her family in New Zealand when she was 3, back in 1999. She had DACA until 2015 when it expired. She married a citizen in May 2018. What does she need to file? I-130 from her husband and the I-130A for her and the I-751 all at once?

Also, her New Zealand birth certificate has her mom's name spelled wrong and her dad's birthday is wrong. Dad is deceased. Mom is a dual citizen of Tonga and New Zealand and travels back and forth to the US legally on visas (never has overstayed). Should she put the info on the forms according to the birth certificate she has or the correct way on her mom's passport? (dad is deceased).
