          Appeal from the United States District Court
               for the Northern District of Texas

Before JOLLY, EMILIO M. GARZA, and PARKER, Circuit Judges.

PER CURIAM:*

     Juan Ventura Vera (“Ventura”), an excludable alien who

arrived in the United States in the 1980 Mariel boatlift from

Cuba, appeals the denial of his 28 U.S.C. § 2241 habeas corpus

petition, in which he challenges his continued detention by the

Immigration and Naturalization Service (“INS”).   The INS most

recently took Ventura into custody in 1999, after he completed a

prison term for first-degree assault in Missouri, the latest

conviction in his extensive criminal history within the United


     *
        Pursuant to 5TH CIR. R. 47.5, the court has determined that
this opinion should not be published and is not precedent except
under the limited circumstances set forth in 5TH CIR. R. 47.5.4.

States.    In his habeas petition, Ventura argued that the INS

seized him without a warrant in violation of the Fourth

Amendment, that his continued detention violated his due process

rights and right to be free from cruel and unusual punishment,

and that he was being forced to work in violation of his

Thirteenth Amendment right to be free from involuntary servitude.

The district court rejected his due process and Eighth Amendment

claims on the merits, concluded that he had waived his Fourth

Amendment claim by failing to appeal from the INS’s removal

order, and failed to address his Thirteenth Amendment claim.

     This court reviews de novo the district court’s dismissal of

a habeas corpus petition challenging the detention of an excluded

alien.    Gisbert v. United States Attorney General, 

,

1440 (5th Cir. 1993) (addressing similar due process claims by

Mariel detainees), as amended by, 

(5th Cir. 1993).

We held in Gisbert that an excluded alien’s substantive due

process rights have not been violated because the indefinite

detention is not a “punishment.”     

  In addition,

because the Attorney General has discretion to grant or deny

immigration parole, Ventura has no liberty interest in

immigration parole.    

Supreme Court, in the

recent Zadvydas v. Davis, 

(2001), held that a

deportable alien may contest his continued detention in a 28

U.S.C. § 2241 proceeding, the Court distinguished the status of

deportable aliens from that of excludable aliens like Ventura.

See 

692-94.

                                 -3-

     Ventura’s failure to dispute the district court’s conclusion

that he has waived his Fourth Amendment challenge is tantamount

to a failure to appeal the basis upon which this claim was

dismissed.    See Brinkmann v. Dallas County Sheriff Abner, 

, 748 (5th Cir. 1987).

     Although the respondents and district court failed to

address Ventura’s Thirteenth Amendment claim below, Ventura’s

allegations regarding his work requirements remain too vague to

establish that he is being subjected to “slavery” or “involuntary

servitude.”   See Watson v. Graves, 

, 1552 (5th Cir.

1990); Channer v. Hall, 

, 217-18 (5th Cir. 1997).

     The judgment of the district court is AFFIRMED.   All

outstanding motions are DENIED.
