Scope and purpose
The provision addresses a marriage entered to evade immigration law and specified attempts or conspiracies. The agency must assess the evidence under the applicable legal standard; an adverse credibility issue is not automatically the same finding.
Related rules and practical context
Form I-130 and later petitions can be affected by the record of a previous case. Distinguish this bar from removal of conditions under INA §216 and from other inadmissibility grounds. Explain genuine inconsistencies with evidence rather than manufacturing a record.
