Federal Court Cases Against Unreasonable USCIS Delays
You probably have never heard of the Writ of Mandamus. Your immigration case
could be delayed or denied for many reasons. Sometimes, the U.S.
Citizenship and Immigration Services (USCIS) can cause a delay because of a
lost file or a request for evidence. Extended delays are usually related to
FBI security checks.
USCIS has a mandatory legal duty to make a decision on all immigration
applications; however, USCIS often delays the adjudication of a case,
especially when filing an adjustment of status and in Citizenship cases.
Despite repeated inquiries for case status updates, many people are advised
by USCIS simply that their case is “under review” or “still pending”.
