You need to look at your GCMS notes and read analyst notes for what the problem is. If it can be solved by providing some supporting documents then do it asap. For example, my police certificate was under review required so I uploaded an authority letter that I provided to my father to get that certificate on my behalf. Once I uploaded it, they cleared the review. So if you can upload some supporting documentation do that asap.300 days passed and no info, RR for criminal as per GCMS.
