The USICS issued a final policy memorandum clarifying who can sign immigration forms. The February 15, 2018 memo, confirmed that “petitioners and applicants who seek immigration benefits must provide a valid signature on forms submitted.” The USCIS will no longer accept Power of Attorney signatures. For applications filed by corporations or other legal entity, they must be signed by an authorized person. The memo provides a list of individuals authorized to sign on behalf of corporations.
There are limited exceptions to this new regulation such as when the applicant/petitioner is disabled or younger than 14 years of age.
Otherwise, the USCIS will no longer accept forms signed by attorneys or representatives based on a signed G 28 Notice of Entry of Appearance.
