Final answer:
Customs officers do not verify passports and visas using microscopes.
Step-by-step explanation:
The statement is False. Customs officers do not verify traveler's passports and visas for authenticity using microscopes. Instead, they use various security features present on passports and visas, such as holograms, watermarks, and special inks, to authenticate them. These security features are designed to prevent counterfeiting and make it easier for officers to identify fake documents.
