Nonimmigrant visas are for international travelers, (citizens of other countries), coming to the U.S. temporarily. This visa allows you to travel to a U.S. port-of-entry (airport, for example) and request permission of the Department of Homeland Security immigration inspector to enter the U.S. A visa does not guarantee entry into the United States.

International travelers come to the U.S. for a wide variety of reasons, including tourism, business, medical treatment and certain types of temporary work. The type of visa needed is defined by immigration law, and relates to the principal purpose of your travel. For an overview of the types of nonimmigrant visas available under immigration law, please see Nonimmigrant Visa Classifications on the USCIS website. The Consular Officer at your embassy or consulate will decide what kind of visa you need, when you apply.
 

Green Cards through Investment (also called the Fifth Preference Green Card or EB-5) are available to anyone who invests a certain amount of money in the United States by creating a business or expanding one that already exists.

The investor must be active in the management of the company. A number of investors may join together in creating or expanding a U.S. business so that each applicant may qualify for an Investor Green Card through one single company. However, the individual investment of each applicant must still meet the minimum qualifying amount, and each investor must be separately responsible for the creation of new jobs.
