In short, no, calling the USCIS will not speed up the process. It's best if you just check the status online. You can go to the USCIS website, enter in your USCIS case number and you can obtain the case status right online. Just calling in to the USCIS is probably just going to make you lose your mind and get more frustrated. You are likely to be on hold for extended periods of time. We've heard feedback from some customers claiming that they waited on hold for several hours, only to receive an unsatisfactory scripted response that is regurgitated from the website itself.
Once you reach an agent to ask about the status of your case, they'll simply read you what you could have seen yourself on the link above. In most cases, you'll be talking with a low-tiered call center rep, not the actual processing center.
To get real answers, you will want to schedule an InfoPass. But to caution you, not all InfoPass meetings are satisfactory. Often times, you are left with the same "hurry up and wait" jargon you get from calling in. But if your case is abnormally delayed, even beyond the standard delays that have been widespread since 2018, you have nothing to lose with scheduling an InfoPass to at least try to get some answers.
Definitely keep up on your case status and don't let too much time go by without getting solid answers. Keep all your documents with you, including your notice of action documents, for reference.
