Communicating with lady from russia online total est. Cost to bring her here and length of time until visa would expire

Sounds like she is scamming you Randell. She can get this information from the American consulate where she lives, or her own Immigration.

Is she asking you for money to come to see you ? If so, don't send her any, it is a scam.

Tick

She will get a passport from her nation, and a visa from the US embassy there. So she now "loves" you, right,
I would send nothing till you went there and visted her first.
