Just heard from a friend who is applying for her second child's PR sticker right now that HK Immig is taking super long to deliver. She got the one for her first daughter a couple of years ago and it was relatively straightforward but she's been waiting for over two months for her younger son. Apparently Immig told her that they are swamped with fast-tracking working visas for the Japanese right now and everything is put on the backburner.
