My wife and I will initially move in with my dad in the US. I am the US citizen and have been living abroad for some years. I kept my US drivers license, bank / investment accounts, auto insurance, and always filed US taxes. I have prepared my I-864 and my dad will be a join sponsor and has prepared an I-864. We intent to live with him for a month or so while we out own place -- does this necessitate that we use an I-864a because we will, for a short time, be a household? Of course now we are not one household as my wife and I are still abroad.
Hope this question makes sense... 😕
