"In an effort to take the lessons learned from our pandemic posture, USCIS has been evaluating which flexibilities can and should be extended permanently. As a result of this evaluation, the reproduced signature flexibility announced in March, 2020, will become permanent policy on July 25, 2022."
Individuals or entities who submit documents with an electronically reproduced original signature must retain the original “wet signature” documents, as the agency may, at any time, request an original document. Failure to provide this document may negatively impact case adjudication.
USCIS does not accept electronically signed documents that are signed through DocuSign or similar applications that affix an electronic signature.
25 июля 2022 USCIS опубликовал сообщение о том какие именно электронные подписи на документах они принимают, и какие не принимают.
Документ должен быть подписан от руки, отсканирован и предоставлен как копия оригинала подписи. Электронные подписи не принимаются по прежнему.
Тут более подробно и тут. Here is more information. Also, here.
