I want to know about getting the citizenship through investor program?.. time? ..cost?.. risks?

That is a very big question for a small email post. I suggest you research the program or consult with an experienced immigration attorney who focuses on such cases. In general, there are many programs, time varies depending on the program, cost varies depending on the program you select and the attorney who you work with and there is always risk. It to may vary.

You will need to invest either $1,000,000 or $500,000 in order to pursue lawful permanent residence through the investor visa program. The actual amount you must invest will depend upon how you are looking to invest and where. You will first be granted lawful permanent residence on a conditional basis. You will be a conditional resident for a period of two years. At the end of the two year period, you will need to request removal of conditions. To do so, you must be able to document you have invested the capital, there has been a sustained investment and jobs have been created. If you meet this criteria, you will be issued a ten-year green card. You may apply for naturalization after being a lawful permanent resident for five years. You should consider discussing your situation with an experienced immigration attorney.

You can start your research on www.uscis.gov or you co do better than that and schedule a consultation with one of the fine immigration lawyers answering questions here on . May offer consultations on Internet media or phone.
