The indictment or information need not be pending in another
district
at the time of arrest in order to be subject to a Rule 20 disposition.
O'Brien v. United States, 233 F.2d 246 (5th Cir. 1956); Hornbrook
v.
United States, 216 F.2d 112 (5th Cir. 1954). If a complaint only is
pending
in another district, Rule 20 may still be used. The person arrested, held,
or
present must state in writing that he or she wishes to plead guilty or nolo
contendere, to waive venue and trial in the district in which the warrant
was
issued, and to consent to disposition of the case in the district where
arrested,
held, or present, subject to approval of the United States Attorney for each
district. Upon filing the written waiver of venue in the district in which
defendant is present, the prosecution may proceed as if venue were in such
district, i.e., charges may be filed there.
