Can a Pennsylvania lawyer ask about or threaten to report a witness's or party's immigration status?

Plain-English summary

The Committee issued the opinion in response to increased inquiries about attorneys questioning or invoking participants' immigration status. It concurs with the Philadelphia Bar Association's Formal Opinion 2025-1. The opinion concludes that overt or implied threats to invoke immigration status, or actual reports to authorities, violate Rules 3.4(a), 3.4(d), 4.4(a), and 8.4(d) when intended to prevent participation in the legal system.

The analysis turns on the lawyer's purpose. The opinion says a lawyer may legitimately explore a witness's background, bias, or credibility and seek to admit relevant evidence. Under Rule 4.4(a), an immigration-status inquiry intended to uncover relevant case information is permitted; introducing that status solely to coerce or intimidate is prohibited.

The opinion says invoking immigration status to suppress participation in proceedings undermines the adversary process and is prejudicial to the administration of justice under Rule 8.4(d). It treats implied invocations like overt threats when they serve that purpose. It also cites Pennsylvania Rule of Evidence 413, which restricts immigration-status evidence unless status is an essential fact, and observes that the act of reporting lawful status to immigration authorities is not itself prohibited by law.

In practice

Under this opinion, a Pennsylvania lawyer may inquire into a person's immigration status when the purpose is to uncover information relevant to the matter, but may not reference, inquire into, or report that status in order to coerce, intimidate, or deter the person from offering evidence or pursuing a claim. The opinion treats implied threats the same as overt ones, and applies the prohibition to actual reporting to immigration authorities when done for that purpose.

Common questions

Q: Can I ever ask a witness about immigration status?

A: Per the opinion, yes, if the inquiry is intended to uncover information relevant to the case; the opinion says a lawyer may explore a witness's background, bias, or credibility and seek to admit relevant, admissible evidence.

Q: What makes the same inquiry a violation?

A: The opinion says purpose controls. Introducing status solely to coerce or intimidate violates Rule 4.4(a), and invoking it to deter participation also violates Rules 3.4(a), 3.4(d), and 8.4(d).

Q: Does it matter that I only implied it rather than making a direct threat?

A: No. The opinion concludes that the Rules reach implied as well as overt invocations when the lawyer's purpose is to deter participation.

Q: Is reporting someone's status to immigration authorities itself prohibited?

A: The opinion observes there is "no law that prohibits reporting a person's lawful status," but reporting undertaken to prevent participation in the legal system is prohibited under the Rules.

Background and rules framework

The opinion interprets Pennsylvania Rules of Professional Conduct 3.4(a) and 3.4(d) (fairness to opposing party and counsel), Rule 4.4(a) (respect for third persons' rights), and Rule 8.4(d) (conduct prejudicial to the administration of justice). It also cites Rule 4.3(a) while discussing implied assertions and Pennsylvania Rule of Evidence 413 on immigration-status evidence.
