Dad got his 10 years card since last year. Yes he went through Lagos interview. When she filed a petition for my Dad they both thought I will follow as an accompany but this changed when the USCIS advised that my step mom must filed a fresh petition. So, the petition was filed and I was Documentarily Qualified the day my dad was to fly to the US.
The are already divorced with a decree of dissolution.
Dad called her and she said they will discuss better today.
