Before REAVLEY, JOLLY, and JONES, Circuit Judges.

PER CURIAM:*

     Man    Khac       Nguyen     (Nguyen)       appeals   the   district      court’s

dismissal    of     his     Federal    Tort       Claims   Act   (FTCA)     negligent

investigation and false imprisonment claims against the Immigration

and Naturalization Service (INS).                   Because under the FTCA the

United States has not waived its sovereign immunity with respect to

the actions of the INS in this case, we AFFIRM.

     It     is    undisputed       that     Nguyen    satisfied    the      statutory

requirements      of    8   U.S.C.    §    1432(a)(repealed)       for     derivative


     *
       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this opinion should not be published and is not precedent except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.

                                             1
citizenship when he entered the United States in 1993: at the time

of his legal entry he was unmarried, his father had died before he

was eighteen and his mother was a United States citizen.                  However,

Nguyen did not claim derivative citizenship, apparently because he

was unaware that he qualified.

     In 1995 and 1996, Nguyen was convicted of a number of felonies

that under INS regulations are considered aggravated felonies.

While in jail, Nguyen was identified by an INS agent as a possible

deportable alien.       Nguyen affirmed his deportability when he, as a

convicted felon, told the INS officer that he was born in Vietnam,

was a citizen of Vietnam, and had permanent resident alien status.

Based on the information furnished by Nguyen, the INS officer began

a file on Nguyen.       As part of the process, he requested Nguyen’s “A

file” which contained documents relating to Nguyen’s entry into the

United States.      However, Nguyen’s “A file” was unavailable because

of a building closure where the file was located.

     After     Nguyen     served    his       sentence,   the    INS   instituted

deportation     proceedings        against      him.      At    the    deportation

proceedings, Nguyen was represented by counsel and was assisted by

an interpreter.       At no time did he make a claim of derivative

citizenship or challenge the allegations against him.                      At the

conclusion     of   the    hearings,      the     immigration     judge    ordered

deportation.     The decision was based on ample evidence undisputed

by Nguyen or his attorney.                That decision was not appealed.



                                          2
Pending deportation, Nguyen was held in INS custody. Approximately

fifteen months later, a new attorney made an appearance on behalf

of   Nguyen.    At   last,    the   new      attorney   asserted    a   claim     of

derivative citizenship for Nguyen.              The INS released Nguyen ten

days   later.    Nguyen      thereafter       applied   for   and    obtained      a

certificate of citizenship.

       In March 2000, Nguyen brought suit under the FTCA seeking

damages.    He alleged that the INS agents were negligent in not

investigating   properly      and   in    not   recognizing   that      he    was a

derivative citizen and that he was unlawfully detained.                      After a

two-day bench trial, the district court dismissed the case with

prejudice for lack of jurisdiction.

       This court reviews a district court’s finding that it lacked

jurisdiction de novo.        Foster v. Townsley, 243 F.3d 210, 213 (5th

Cir. 2001).     Although the district court found that it lacked

jurisdiction on several grounds, we address and affirm only the

sovereign immunity ground.

       Congress has waived the sovereign immunity of the United

States for particular kinds of tort suits under the FTCA.                       That

waiver, however, is subject to several express limitations, which

means that in those express situations the federal courts have no

jurisdiction over the United States in FTCA cases.                  One of these

limitations is the discretionary function exception, which provides

that courts have no jurisdiction over claims against the United



                                         3
States “based upon the exercise or performance or the failure to

exercise or perform a discretionary function or duty on the part of

a federal agency or an employee of the Government, whether or not

the discretion involved be abused.” 28 U.S.C. § 2680(a). Decisions

to   investigate,   how    to   investigate         and    whether      to    prosecute

generally fall within this exception. See Sutton v. United States,

819 F.2d 1289, 1293 (5th Cir. 1987); Smith v. United States, 375

F.2d 243, 247-48 (5th Cir. 1967).                   However, the discretionary

function exception does not necessarily shield the government from

liability   for   intentional     torts,          such   as    false    imprisonment,

perpetrated by its investigative or law enforcement officers.                         See

28 U.S.C. § 2680(h).       This court has recognized that §§ 2860 (a)

and (h) exist in tension with each other and that their purposes

must be harmonized in each individual case, so as to give each

provision meaning without abrogating either provision. Sutton, 819

F.2d 1289, 1295. In this connection, this court has not “hesitated

to conclude that [an] action does not fall within the discretionary

function of § 2680(a) when governmental agents exceed the scope of

their authority as designated by statute or the Constitution.”

Sutton, 819 F.2d 1289, 1293.

      In   harmonizing    the   two   provisions          in    this    case,    it   is

significant that the INS officers did not commit a constitutional

violation   nor   did    they   engage       in    any    conduct      that   could    be

described as in bad faith.       No regulation or statute prevented the



                                         4
INS agents from pursuing deportation proceedings against Nguyen

based on the information available to them.           Regulations expressly

allow INS agents to make arrests if the agent “has reason to

believe that the person to be arrested...is an alien illegally in

the United States.”     8 C.F.R. § 1287.8(c)(2)(i).          The INS agents in

this case had sufficient reason to believe, based on repeated

admissions, explicit and implicit, by both Nguyen and his attorney,

that Nguyen was an alien.       Consequently, the detention is not of a

character for which a court should refer to § 2680(h) for an

exception to the discretionary function. With respect to the claim

of negligence in investigating, the only basis asserted is failing

to obtain Nguyen’s “A file” and failing to otherwise determine from

various     documents   that    Nguyen     was    entitled     to    derivative

citizenship.       Because   there   is    no   allegation    or    evidence   of

intentional misconduct, this is essentially a claim that the INS

officers failed to adequately perform a discretionary duty, which

falls   squarely    within     the   discretionary     function      exception.

Because the INS agents in this case did not exceed their authority

either in investigating the case or in detaining Nguyen, their

actions are protected by the discretionary function exception of

the FTCA.

     For the foregoing reasons, the judgment of the district court

is

                                                                     AFFIRMED.
