Obtaining residence by marriage


Hi everyone,
My fiancé and I are planning to get married in Argentina as soon as I can travel there from the US... whenever that may be. She is Argentinian. After we are married we wanted to apply for me to get a residence card.

As I understand now I would need to apostille a birth certificate as well as a FBI background check. Are their any other documents I need to prepare before I travel to Argentina. And any idea on how long those documents are valid for after being apostillised?

Thanks in advance for any help!
