Starting this week, foreigners entering U.S. airports and seaports will have their fingerprints scanned and their photographs taken.
It's part of a new program to tighten border security. The program is called U.S.-Visit, or U.S. Visitor and Immigrant Status Indicator Technology. It's estimated the program will check 24 million foreigners each year, though some will be repeat visitors. Under the program, customs officials can instantly check an immigrant or visitor's criminal background.
The only exceptions will be visitors from 28 countries, mostly European, whose citizens are allowed to come to the United States for up to 90 days without visas.
