In March 2005 a completely electronic labor certification system, PERM (Program Electronic Review Management), came into use. PERM was intended to reduce labor certification times to under 60 days. However, PERM may be creating as many backlogs as it is intended to solve. Because of congressionally mandated annual quotas, there may not be enough visas available to grant green cards to everyone who is approved by PERM, which may have played a role in the retrogression of priority dates on September 13, 2005.
