The substantive removability ground is INA section 237(a)(1)(D)(i): an alien whose conditional permanent resident status has been terminated under section 216 is deportable. That ground depends on the underlying termination being valid, which is not the same thing as the underlying termination having been issued. INA section 246(a) addresses rescission of adjustment in some adjacent contexts.
The standard of review for a terminated conditional residence in immigration court is de novo, as set out in Matter of Herrera del Orden. The case arose in the marriage-based context but applies to EB-5 conditional residents as well. The immigration judge reviews the record fresh, with full panoply of rights including the right to introduce new evidence not before USCIS. This is one of the most important features of the post-denial landscape: a denial that looks final at USCIS is, in a meaningful sense, the start of a separate proceeding rather than the end of the case.
Matter of Lock supports the position that the NTA's allegation of "termination of conditional residence" is admissible-as-USCIS-action but deniable-as-actual-status. The strategy is to admit that USCIS issued a termination notice and deny that the residence is, as a matter of law, actually terminated. This shifts the burden to DHS to prove termination by clear and convincing evidence, which it often cannot do on a record that supports approval under de novo review.
Subpoena authority in immigration court is set out in 8 C.F.R. section 1003.35. EB-5 removal-defense practitioners use subpoenas (or motions for subpoenas) to request the adjudicating IPO officer's testimony or records. Practitioners report that even denial of a subpoena motion can establish that DHS, not the respondent, bears the burden of proving the basis for termination.
Hui Ran Mu v. Barr, 936 F.3d 929 (9th Cir. 2019) supports the proposition that EB-5 dependents may litigate or renew the I-829 in removal proceedings even though they were not the petition filer. The case is binding within the Ninth Circuit and persuasive elsewhere.
Beyond the I-829 contest itself, three additional avenues are typically considered. LPR cancellation of removal under INA section 240A(a) is available where the respondent has had seven years of continuous residence and five years as a lawful permanent resident, including conditional residence. Family-based adjustment via I-130 is a parallel track for respondents with qualifying U.S.-citizen or LPR family members. Federal-court mandamus on the I-829 itself is available under the 90-day statutory adjudication target in INA § 216A(c)(3)(A) where the agency holds a refiled or pending matter beyond the statutory period.
The current administration has assigned some active-duty Judge Advocate General officers to serve temporarily as immigration judges. There is a serious Posse Comitatus argument (18 U.S.C. section 1385 and related authorities) that JAG officers may not constitutionally adjudicate civil immigration matters. Practitioners file motions to disqualify at the master calendar to preserve the issue. Failure to raise the motion at the master calendar can waive the argument for federal-court review.
