We submitted our application in mid Jan 2017 and sponsorship approval was very fast, but things seem to have slowed down since the application reached Hong Kong. Our case is as straightforward as they come (applicant is from UK, married over 15 years, 2 Canadian children, living together in HK) but our background check hasn't even started yet even though they started processing the application over 3 months ago.
Me too. We submitted our application in mid Jan 2017 and sponsorship approval was very fast.
Now we don't get any update from HK.
