I want to set up a business in partnership with a US citizen and subsequently immigrate to USA.Whats the way?

From the USCIS website, here are the guidelines on how to immigrate to the US via investment http://uscis.gov/graphics/services/residency/inves...

Who have invested -- or who are actively in the process of investing -- in a new commercial enterprise:

at least $1,000,000, or

at least $500,000 where the investment is being made in a "targeted employment area," which is an area that has experienced unemployment of at least 150 per cent of the national average rate or a rural area as designated by OMB

If the amount is too stiff for you, maybe an option would be employment-based immigration. The business that you will set up with your US citizen partner can petition you and apply for employment-based green card for you.

It is better though to consult an immigration lawyer.

Go To Yahoo! Groups, register then after it, find the specific field of Interest, be a member then post a message about you want then wait for a while because you will be answered or if not go to several free dating websites like FaceParty, MySpace.com or plentyoffish.com. try it...

Do you have at least $500,000.00 USD to invest in the United States of America?

If you do, you can get an Investor Visa.

If you don´t I can find you a "wife" if you know what I mean.

If you invest a certain amount of money in the US, there is a special program to fast-track you. I forget the amount, sorry.

You could always marry the US citizen

I would say do not immigrate to USA.

its all fulled up here. no room.

it would be better for you to start you business in your country. they most likley need jobs there.
