According to Business Insider, the most recommended tip from experienced business travelers for surviving life on the road is to utilize Global Entry.
Global Entry is a U.S. Customs and Border Protection program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States. Participants may enter the United States by using automated kiosks located at select airports. Program participants simply present their machine-readable passports, place their fingertips on the scanner for fingerprint verification, and make a customs declaration.
Global Entry applicants must undergo a rigorous background check and interview before enrollment. Visit the U.S. Customs and Border Protection website for more information and Global Entry enrollment center locations.
