US Immigration from Ghana

Please a friend wrote her mailing address as this.

P.O.BOX 10

She didn't bring space between "O." and "BOX"

Would she be disqualify because of how he wrote it?

I received my NVC letter with case and invoice numbers last week. I logged on to the CEAC successfully once. Since then i cant log on to make my payment again. What should I do pls?

How would you know if someone is married in a different country? I was recently the victim of a second marriage. He had a wife in South Africa and married me in Ghana. If she hadn t contacted me I would never have found out. How do you protect yourself from theses types of things? I hope I m asking this question in the right form. Thank you
