Which authority allows customs officers to conduct extended border searches?

The correct answer is based on authority regarding the powers of customs officers specifically related to border searches. The code mentioned, 19 USC §482, establishes the authority for customs officers to conduct thorough inspections and searches of individuals and their belongings at the borders and entrances of the United States. This statute grants customs officials the necessary legal backing to perform extended searches, which can include items in a person’s possession and any accompanying baggage.

The underlying purpose of this authority is to enforce restrictions on illegal goods and ensure compliance with customs regulations. Customs officers use this power to enhance security and protect the economy from threats posed by contraband, smuggling, and other illegal activities entering the country.

The other options, while related to immigration and enforcement, do not specifically provide the same authority for customs officers to carry out extended searches at the border. They refer to other aspects of immigration control or authority but lack the specific focus on customs inspections as outlined in 19 USC §482.
