Yes, I'm 7 May applicant and completed medicals mid-November and have heard nothing since then. I did have to renew passports for a couple members of my family and sent a CSE with copies of new passports, so that may slow me down a bit, but still it's getting to be a long wait.
I noticed a pattern from the spreadsheet. In October and November, there were some lucky applicants who did their medicals and very quickly got their RPRF request within a few days and then got visas a few days after paying. It all happened very fast. That accounts for the few visas issued so far to those on the spreadsheet. However, since then there has been nothing even for other people who did medicals in November like my family did. There are several waiting since completing medicals in November or even late October. I've requested information from them if they have any. On the one hand it makes me feel a little better that it is probably not a problem with my application that is causing the delay. But on the other hand, what is going on at HKVO??
