Decision: Leng May Ma v. Barber, 357 U.S. 185 (1958).

Leng May Ma v. Barber considered whether a person physically released into the United States on immigration parole had been admitted or had entered for purposes of a statutory provision governing detention and removal to a country where the person would face physical persecution.

Parole allowed physical release while inspection continued

The governing law authorized temporary parole for emergent reasons or reasons deemed strictly in the public interest. It expressly provided that parole was not an admission and that the person would continue to be treated as an applicant at the border.

Physical presence did not determine legal entry

The Court applied the historical rule treating this applicant as legally at the border despite physical release. Although the petitioner was outside a detention facility, parole did not change the legal posture of exclusion or create the status of a person who had entered.

The particular withholding provision did not apply

On June 16, 1958, the Court interpreted former section 243(h), 8 U.S.C. § 1253(h), which protected an alien within the United States from specified deportation. The petitioner had arrived claiming citizenship, received parole while that claim was considered, and later been ordered excluded. She did not challenge the exclusion order in this case. 357 U.S. at 185–188. Because her parole did not convert exclusion into entry, the Court held that provision unavailable under the law then in force.

Current cases must use the current statute

Congress has since revised immigration terminology, procedures, and protection provisions. The enduring parole principle remains important, but modern claims must be analyzed under current sections governing admission, parole, asylum, withholding, and Convention Against Torture protection.

Key takeaways

• Distinguish physical release from legal admission.
• Identify the current statute and whether the person is seeking admission or defending against removal; do not replace that analysis with a physical-presence label.
• Do not use this historical holding to bypass current protection provisions.
• Preserve the parole document, charging papers, arrival record, and protection evidence.
