1. Get global entry and TSA pre-check
If you've ever gone through customs, you know how brutally long that wait can be. One of the most effective ways to make international travel smoother is to get Global Entry status. This program, run through the U.S. Customs and Border Protection, will get you expedited customs processing at U.S. airports. You'll have to attend an in-person interview after passing a background check, but it's worth it. Once you gain Global Entry, you automatically receive TSA PreCheck to bypass lines and get quicker security checks. Global Entry saves time and hassle for frequent travelers domestically as well.
