Delays with Deloitte H1B CoE process

Engineer in Consulting

Hello, first time posting in this community. I'm an engineer who recently took an offer for a Sr. Consultant role in Deloitte (US). At this time I'm working through their immigration attorneys to transfer my visa over to the new place of employment; however there have been some delays in Deloitte acquiring specific information from clients which have held the process up. I was curious whether anyone else had experienced this or heard anything about Deloitte US having issues with their international employees? Has anybody else gone through the CoE process with the company?
