Yes.
No visa is required to buy property but to enter the US, you would need at least a b-2 visitors visa.
Not automatically. You have to get the appropriate visa and documents.
A US citizen would have to apply for a visa and become resident. Alternatively they could marry a UK citizen. In addition a British Company could invite the US citizen to work in the UK and apply for a work visa on their behalf. There are quite a few ways to do it legally.
Only way is if you get a visa in Philipenes and Sri Lanka is your nationality so you're therefore a citizen for that country. If you have kids in the Phillipenes, They would become a Filipino citizen, just saying.
No, visas are only available from a U.S. embassy/consulate. You CANNOT walk up to the border and get a visa. Moreover, they will not issue a visa if you are from a 3rd country. That means that you would need to get a visa at the U.S. embassy in Ankara.
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.
visitors visa
nothing she tills has to become a citizen
No, a K1 visa is not needed to travel out of the country. a K-1 Visa is a Visa issued to someone engaged to an American citizen so that they can enter America. The person must then marry the American citizen within 90 days of entry into the US and can then get a green card and become a legal citizen of the United States.
