CHEUNG SUM SHEE ET AL.
v.
NAGLE, COMMISSIONER OF IMMIGRATION.
No. 769.
Supreme Court of United States.
Argued April 17, 20, 1925.
Decided May 25, 1925.
ON CERTIFICATE FROM THE CIRCUIT COURT OF APPEALS FOR THE NINTH CIRCUIT.
*337 Mr. Frederick D. McKenney and Mr. George A. McGowan, with whom Messrs. John L. McNab, Jackson H. Ralston, Roger O'Donnell, George W. Hott, W.J. Peters, M. Walton Henry, J.P. Fallon, O.P. Stidger, W.G. Becktell, and Gaston Straus were on the brief, for appellants.
Mr. Assistant Attorney General Donovan, with whom the Solicitor General was on the brief, for appellee.
Mr. Henry W. Taft filed a brief as amicus curiae by special leave of Court.
*343 MR. JUSTICE McREYNOLDS delivered the opinion of the Court.
Petitioners are alien wives and minor children of resident Chinese merchants lawfully domiciled within the United States. They departed from China on the Steamship President Lincoln, and upon arrival at San Francisco, July 11, 1924, sought permanent admission to the United States. The Secretary of Labor denied their applications and gave the following reasons therefor 
"Neither the mercantile status of the husband and father, nor the applicant's relationship to him, has been *344 investigated for the reason that even if it were conceded that both these elements exist the applicants would be inadmissible as a matter of law. This is made necessary because of the inhibition against their coming to the United States as found in Paragraph (c) of Section 13 and that portion of Section 5 which reads as follows: `An alien who is not particularly specified in this Act as a nonquota immigrant or a non-immigrant shall not be admitted as a non-quota immigrant or a non-immigrant by reason of relationship to any individual who is so specified or by reason of being excepted from the operation of any other law regulating or forbidding immigration.'"
The court below has inquired, Jud. Code § 239: "Are the alien Chinese wives and minor children of Chinese merchants who were lawfully domiciled within the United States prior to July 1st, 1924, such wives and minor children now applying for admission, mandatorily excluded from the United States under the provisions of the Immigration Act of 1924?"
Prior to July 1, 1924, petitioners, if otherwise unobjectionable, might have been admitted notwithstanding their race and nationality. United States v. Mrs. Gue Lim, 176 U.S. 459, 466, 468; Yee Won v. White, 256 U.S. 399, 400, 401. But it is said they are absolutely excluded by the "Act to limit the immigration of aliens into the United States, and for other purposes," approved May 26, 1924, c. 190, 43 Stat. 153, applicable provisions of which follow 
"Sec. 13. . . . (c) No alien ineligible to citizenship shall be admitted to the United States unless such alien (1) is admissible as a non-quota immigrant under the provisions of subdivision (b), (d), or (e) of section 4, or (2) is the wife, or the unmarried child under 18 years of age, of an immigrant admissible under such subdivision (d), and is accompanying or following to join him, or (3) is not an immigrant as defined in section 3."
"Sec. 3. When used in this Act the term `immigrant' means any alien departing from any place outside the *345 United States destined for the United States, except . . . (6) an alien entitled to enter the United States solely to carry on trade under and in pursuance of the provisions of a present existing treaty of commerce and navigation."
"Sec. 5. When used in this Act the term `quota immigrant' means any immigrant who is not a non-quota immigrant. An alien who is not particularly specified in this Act as a non-quota immigrant or a non-immigrant shall not be admitted as a non-quota immigrant or a non-immigrant by reason of relationship to any individual who is so specified or by reason of being excepted from the operation of any other law regulating or forbidding immigration."
The present existing treaty of commerce and navigation with China, dated November 17, 1880, 22 Stat. 826, 827, provides 
"Article II. Chinese subjects, whether proceeding to the United States as teachers, students, merchants or from curiosity, together with their body and household servants, and Chinese laborers who are now in the United States shall be allowed to go and come of their own free will and accord, and shall be accorded all the rights, privileges, immunities, and exemptions which are accorded to the citizens and subjects of the most favored nation."
An alien entitled to enter the United States "solely to carry on trade" under an existing treaty of commerce and navigation is not an immigrant within the meaning of the Act, § 3(6), and therefore is not absolutely excluded by § 13.
The wives and minor children of resident Chinese merchants were guaranteed the right of entry by the treaty of 1880 and certainly possessed it prior to July first when the present Immigration Act became effective. United States v. Mrs. Gue Lim, supra. That Act must be construed with the view to preserve treaty rights unless clearly *346 annulled, and we cannot conclude that, considering its history, the general terms therein disclose a congressional intent absolutely to exclude the petitioners from entry.
In a certain sense it is true that petitioners did not come "solely to carry on trade." But Mrs. Gue Lim did not come as a "merchant." She was nevertheless allowed to enter, upon the theory that a treaty provision admitting merchants by necessary implication extended to their wives and minor children. This rule was not unknown to Congress when considering the Act now before us.
Nor do we think the language of § 5 is sufficient to defeat the rights which petitioners had under the treaty. In a very definite sense they are specified by the Act itself as "non-immigrants." They are aliens entitled to enter in pursuance of a treaty as interpreted and applied by this court twenty-five years ago.
The question propounded by the court below must be answered in the negative.
