Contact the INS. They would be able to help you.
The person cannot just be "sent back" simply because the US citizen has changed his or her mind about the marriage. If the person has the conditional green card, the US citizen can refuse to file the joint petition to remove the conditions, but that does not guarantee that the person will not be able to obtain the permanant greencard. Once a person has legally immigrated to the US, it takes a lot for him or her to be deported. Any US citizen can bring a person to the US, but he/she cannot have the person deported for personal reasons. Marriages fail every day. Whether the ex is allowed to stay in the United States or not is not the concern of the American spouse, but of the INS officer who gets assigned to the case.

No, but the Russian may be able to get a green card but might be required to go back home during the paperwork phase.
No. The person is still subject to the terms of the visa. If the person with the work visa marries a US citizen, it shortens the residency period needed to apply for naturalization, but still does not automaticaly change the visa.
US and UK allow Dual citizenship. A person can be a US citizen and a citizen of UK if he/she desires to. But if a person applies to get naturalized as a citizen of UK when he/she is already a US citizen, then it will lead to losing US citizenship.So a person can have US & UK citizenship as long he/she is not a naturalized citizen of UK.
Once a person from another nation marries a Canadian citizen, he or she becomes a permanent resident. The process takes approximately 50 days for the paperwork.
no depends were they came from
An Indian cannot become a US citizen by marrying a US citizen. Not only Indians, but any other person from another country cannot become a US citizen just by marrying a US citizen. A US citizen can sponsor a Indian on an appropriate visa ( like K-1 visa) after which he/she can adjust their status to that of a permanent resident. After being a PR for 3 yrs, the Indian can then apply for US citizenship, if needed.
