delivered the opinion of the court.

This is a petition for habeas corpus by a Chinese person, alleging that he is detained unlawfully by the General Manager of the Pacific Mail Steamship Company on the ground that he is not entitled to enter the United States. The petition alleges that the petitioner is a resident and citizen of the United[*11] States, born in San Francisco of parents domiciled there, but •it discloses that the Commissioner- of Immigration at the port of San Francisco, after a hearing,' denied his right to land, and that the Department of Commerce and Labor affirmed the decision on appeal. .The petitioner thereupon was placed in custody of the steamship company to be sent to China. So far the case is within United States v. Ju Toy, 198 U. S. 253, and the petition was dismissed for want of jurisdiction (presumably on the ground of that decision), as sufficiently appears from the record, the reasons assigned' for the appeal and the order allowing the same. But the petition further alleges that the petitioner was prevented by the officials of the Commissioner from obtaining testimony, including that of named witnesses, and that had he been given a proper opportunity he could have produced overwhelming evidence that he was born in the United States and remained there until 1904, when he departed to China on a temporary visit. We do not scrutinize’ the allegations as if they were contained in a criminal indictment before the court upon a special demurrer, but without further detail read them as importing that the petitioner arbitrarily was denied such a hearing and such an opportunity to prove his right to enter the country as the statute meant that he should have. The question is whether he is entitled to a writ of habeas corpus on such a case as that.

Of course if the writ is granted the first issue to be tried is the truth of the allegations last mentioned. If the petitioner was not denied a fair opportunity to produce the evidence that he desired, or a fair though summary hearing, the case can proceed no farther. Those facts are the foundation of the jurisdiction of the District Court, if it has any jurisdiction at all. It must not be supposed that the mere allegation of the facts opens the merits of the case, whether those facts are proved or not. And, by way of caution, we may add' that jurisdiction would not be established simply by proving that the Commissioner and the Department of Commerce and[*12] Labor did not accept, certain sworn statements as true, even though no contrary or impeaching testimony was adduced. .But, supposing that it- could be shown to the satisfaction of the District Judge that the- petitioner had been allowed, noth- • ing but the semblance of a hearing, as we assume to be alleged, the question is, we repeat, whether habeas corpus may not be used to give the petitioner the hearing that he has been denied.

The statute's purport to exclude aliens only. They create or recognize, for present purposes it does not matter which, the right of citizens outside the jurisdiction to return to the United States. If one alleging himself to be a citizen is not allowed a chance to establish his right in the mode provided by those statutes, although that mode is intended to be exclusive, the statutes cannot be taken to require him to be turned back without, more. The decision .of the Department is final, but that is on the presupposition that the decision was after a hearing in good faith, however summary in form. As between the substantive right of citizens .to enter and of persons alleging themselves to be citizens' to have a chance to. prove their allegation on the one side and the conclusiveness of the Commissioner’s fiat on thé other, when one or the other must give way, the latter must yield. In sueh a case something must be done, and it naturally falls to be done by the courts. In order to decide what we must analyze a little.

If we regard the petitioner, as in Ju Toy’s case it was said that he should be regarded, as if he had been stopped and kept at the limit of our jurisdiction, 198 U. S. 263, still it would be difficult to say that he was not imprisoned, theoretically as well as practically, when to turn him back meant that he must get into a vessel against his wish and be carried to China. The case would not be that of a person simply .prevented from going in one direction that he desired and had a right to take, all others being left open to him, a case in which the judges were not unanimous in Bird v. Jones, 7 Q. B. 742. But we need not speculate upon niceties. It is true that the petitioner gains no additional right of entrance by being allowed to pass the[*13] frontier in custody for the determination of his case. But on the question whether he is wrongly imprisoned we must look at the actual .facts. De facto he is locked up until carried out of the country against his will.

The petitioner then is imprisoned for deportation without the process of law to which he is given a right. Habeas corpus is the usual remedy for unlawful imprisonment. But on the other hand as yet the petitioner has not established his right to enter the country. He is imprisoned only to prevent his entry and an unconditional release would make the entry complete without the requisite proof. The courts must deal with the matter somehow, and there seems to be no "way so convenient as a trial of the merits before the judge.- If the petitioner proves his citizenship a longer restraint would be ■illegal. If he fails the order of deportation would remain in force.

We recur in closing to the caution stated at the beginning, and add that while it is not likely, it is possible that the officials misinterpreted Rule 6 as restricting the right to obtain witnesses which the petitioner desired to produce, or Rule 7, commented on in United States v. Sing Tuck, 194 U. S. 161, 169, 170, as giving them some control'or choice as to the witnesses to be heard'. But unless and until it is proved to the satisfaction of the judge that a hearing properly so called was denied, the merits of the case are not open, and, wé may add, the denial of a hearing cannot be established by proving that the decision was wrong.

Order reversed:

Writ of habeas corpus to issue.
