There is no regulation defining “independent” for EB-1A letters. USCIS evaluates expert letters under a weight-of-the-evidence approach: submission of letters is not presumptive proof of eligibility, and the agency may accord varying weight based on the letter's relevance, reliability, and overall probative value. That standard comes from Matter of Caron Int'l, 19 I&N Dec. 791, 795 (Comm'r 1988), and Matter of D-R-, 25 I&N Dec. 445, 460 n.13 (BIA 2011). The AAO applied Caron in Matter of Skirball Cultural Center, 25 I&N Dec. 799, 805 (AAO 2012): where the director had not questioned the experts' credentials, their knowledge, or the veracity of their testimony, the AAO found the uncontroverted testimony reliable, relevant, and probative as to the facts in issue.
At the same time, letters are competent evidence that must be considered — an adjudicator may not simply disregard them as self-serving. Courts have long recognized expert opinion letters as probative in this context (Muni v. INS, 891 F. Supp. 440, 446 (N.D. Ill. 1995) ('Better evidence of an alien's extraordinary ability would be difficult to find')), and USCIS Policy Manual guidance directs officers to take into account the probative analysis experts provide, while cautioning that letters which are conclusory or hyperbolic should be discounted (6 USCIS-PM F.2). A federal court enforced that directive in Chursov v. Miller, No. 18-cv-2886 (PKC) (S.D.N.Y. May 13, 2019), holding that USCIS acted arbitrarily when it 'failed to examine the opinion letters for evidence of major significance, directly contradicting its Policy Manual.' Both the Policy Manual and Kurzban's Immigration Law Sourcebook (19th ed., ch. 10) treat a current or former employment relationship as bearing on independence and the author's affiliation as a factor in the weight a letter carries, and favor outside experts who know the beneficiary by reputation and body of work.
Two related doctrines shape how letters are read. Letters that merely repeat the words of the statute or regulation do not carry the petitioner's burden (Fedin Bros. Co. v. Sava, 724 F. Supp. 1103 (E.D.N.Y. 1989)). And where multiple letters share notably similar language or structure, the adjudicator may treat that similarity as a basis for questioning the underlying claims (Matter of R-K-K-, 26 I&N Dec. 658 (BIA 2015)). The converse also holds: an agency may not label detailed letters 'general and broad' where that characterization is 'inconsistent with the actual language' of the letters, as the court held in Golani v. Allen, No. 22-10202 (E.D. Mich. July 31, 2023), where the letters specifically described the petitioner's work as 'novel' and 'unprecedented.'
- Matter of Caron Int'l, 19 I&N Dec. 791, 795 (Comm'r 1988)
- Expert letters are not presumptive proof; USCIS may give them varying weight and may reject a letter not in accord with the record or otherwise questionable.
- Matter of D-R-, 25 I&N Dec. 445, 460 n.13 (BIA 2011)
- Confirms the varying weight given expert testimony based on relevance, reliability, and overall probative value; an author's affiliation goes to weight, not admissibility.
- Matter of Skirball Cultural Center, 25 I&N Dec. 799, 805 (AAO 2012)
- Applies Caron; where the director did not question the experts' credentials, knowledge, or veracity, the uncontroverted testimony was reliable, relevant, and probative.
- Muni v. INS, 891 F. Supp. 440 (N.D. Ill. 1995)
- Recognizes that expert opinion letters are competent evidence an adjudicator must consider — better evidence would be difficult to find.
- Kazarian v. USCIS, 596 F.3d 1115 (9th Cir. 2010)
- Illustrates the conclusory-letter problem: general characterizations of the petitioner do not carry the burden, in contrast to letters that specify a contribution and its effect.
- Chursov v. Miller, No. 18-cv-2886 (PKC) (S.D.N.Y. May 13, 2019)
- USCIS acted arbitrarily by failing to examine the opinion letters for evidence of major significance, contrary to its own Policy Manual, and by weighing the letters in isolation.
- Golani v. Allen, No. 22-10202 (E.D. Mich. July 31, 2023)
- An agency may not dismiss detailed testimonial letters as 'general and broad' when that characterization is inconsistent with the letters' actual language.
- Matter of R-K-K-, 26 I&N Dec. 658 (BIA 2015)
- Notably similar language or structure across letters may be treated as a basis for questioning a petitioner's claims.
- Fedin Bros. Co. v. Sava, 724 F. Supp. 1103 (E.D.N.Y. 1989)
- Repeating the language of the statute or regulation does not satisfy the petitioner's burden of proof.
- 8 C.F.R. § 204.5(h)(3)(v)
- The original-contributions criterion, where expert testimony most often does its work.
- USCIS Policy Manual, Vol. 6, Pt. F, Ch. 2 (6 USCIS-PM F.2)
- Directs officers to weigh the probative analysis of experts, asks that letters set forth the basis of the writer's knowledge and expertise, treats a current or former employer as not independent, and cautions against conclusory or hyperbolic letters.
