I have one more question, my friend was asking me , if there is any free links ,where people can apply for the Green Card, thanks for information

Please clarify, most website links provide free information.

The US Department of State website has information about the Diversity Visa Lottery. I hope this is responsive to your inquiry.

You know when I am trying to sigh up, they asking for money, for the servise, but somebody told me there is Govermment website

Sign up for what? What service do you mean? Please clarify, we need more detail if you want help.

For online servise, like when they register your name and all the information online

Is your friend already in the US or wanting to see if they can immigrate to the US? This site:

USCIS Home Page (http://www.uscis.gov/portal/site/uscis)

Will provide them with information. The information is free, the forms can be downloaded for free, but there will still be fees charged when submitting any forms/applications for approval.

Please clarify what you want. If you cannot, I advise you to consult with an immigration attorney in person. Good luck!
