What does INA 235 allow immigration officers to do at points of entry?

The provision under INA 235 empowers immigration officers to conduct inspections of all aliens at points of entry and to expedite their removal if necessary. This section is critical in maintaining the integrity of the borders and ensuring that individuals who do not meet the legal criteria for entry can be processed swiftly.

By allowing immigration officers to inspect all aliens, INA 235 ensures that they can evaluate each individual's eligibility for entry based on immigration laws. The ability to expedite removal is particularly important for maintaining border security, allowing officers to quickly address and resolve situations where individuals may not have the proper documentation or may pose a risk.

Other options do not align with the scope of authority provided by INA 235. For instance, conducting background checks on citizens or detaining U.S. citizens for questioning falls outside the jurisdiction of immigration officers under this particular section. Similarly, the issuance of temporary visas is not a function of Customs and Border Protection officers, as this is typically the responsibility of consular officers or other designated authorities outside of the border inspection process.
