With the amount of local second officers reaching 4-5 years of service, I wonder why the HKAOA is not actively looking to use that as a reason to block non-hk resident DEFOs from obtaining visas. The dragon guys got the immigration department to make sure they were hired before any more visas were renewed, its possible the same can be done for upgrades? Its to every rank's benefit if DEFOs are blocked. Without DEFOs everyone is harder to replace.
