Yes, customs procedures are conducted at DFW Airport for passengers arriving on international flights. After landing, passengers must proceed through passport control, where their passports are checked and stamped by immigration officers. After clearing passport control, passengers collect their checked luggage and proceed to the customs area. Here, they declare any goods or items they are bringing into the country. Customs officers may conduct inspections or ask questions regarding the items being brought in. Once the customs process is complete, passengers can exit the secure area and continue their journey or connect to domestic flights if necessary.
