Hello,
I am working in Hong Kong and my husband is currently in the UK (where he is a citizen), but coming to join me here soon.
When I arrived to start my new job, he came and we went through basic immigration procedures together, applying for our HK ID cards. He also filled out a form giving me permission to collect his from the main office, which I've done. Now, I have his card with me here, but he's coming for a visit next month (and then leaving again before moving over for good). Does he need it to enter the country, or can he come in without it?
