Hello, here is my experience. We were approved for the I-601 waiver on August 16th, 2024, and had confirmation (from a chat with Emma) that the waiver was sent to the Montreal consulate on August 19th. On December 9th, which is 115 days later, we went to the Congressman office in the city where my husband lives and asked if he could make a request directly to Montreal. The employee told us it wouldn't do anything and was reluctant but sent a request anyway. Two days later, the congressman forwarded us the email he received from the Consulate Correspondence Unit with our instructions (go for new medical and send new police check, photos and passport). So in our case, it seems that it actually did something to send that request. Now we're not sure if I will have to go to a second interview (first interview was in September 2022) but I'll be sending my package through courier on January 7th after my medical and the wait will start again.
