[00:17.04]About 45 million visitors came to the U.S. [00:20.68]between October 1, 2014 and September 30, 2015. [00:27.48]Some were business or pleasure travelers in the U.S. [00:32.12]with visas that expired with time. [00:34.96]Others were in the U.S. under a program that reviews them in advance. [00:40.32]DHS said that by September 30, 2015, [00:45.44]about 416,500 had not left the U.S. [00:52.25]Another 66,500 people stayed past their leave dates, [00:58.76]but later left the U.S. [01:01.16]The number of visitors who overstayed in the U.S. [01:04.40]was lowest among 38 countries [01:07.52]that are part of the Visa Waiver Program (VWP). [01:12.56]VWP allows some travelers into the United States [01:17.72]for tourism or business for 90 days or less without a visa. [01:23.76]Countries with the highest rates of visitors who did not leave were [01:29.08]Djibouti, Bhutan, Burkina Faso and Afghanistan. [01:36.88]The report did not include numbers of visitors that entered by land, [01:41.88]especially visitors from Canada and Mexico. [01:46.04]More than 200 million people entered the U.S. at land border crossings in 2015. [01:54.32]The department says it will try to include them in future reports. [02:00.40]The report did not include the kind of visas recorded in the survey. [02:06.28]DHS says it would like the report to review more F, M and J visas. [02:14.00]An F1 visa allows non-immigrant students into the U.S. [02:21.00]M1 visas are issued to students [02:24.56]who are working in the U.S. or training for a job. [02:29.12]J visas are issued to students in exchange programs. [02:34.92]Congress passed new rules in December [02:38.48]that tighten the waiver program. [02:41.76]Any citizen from Iran, Iraq, Syria or Sudan [02:49.32]-- or anyone who traveled to one of those countries in the past five years [02:54.28]-- is not eligible for a waiver and must get a visa to enter the U.S. [03:01.28]I'm Jim Dresbach.
