Question: I will be travelling to Hong Kong in a few months' time. I hold dual nationality and neither of my nationalities requires a visa to enter Hong Kong. During my trip, I will travel to Korea for a few days, before returning to Hong Kong to fly home.

Will I require a visa as I will have multiple entries within 3 months of first arriving in Hong Kong, or does visa-free entry allow me to come and go (as a tourist), effectively, as I please?

I'm guessing that using my two passports would be something they would spot instantly and lead to further questions?


Answer: Hong Kong: Visa for Multiple Entries?


Question: Last time I visited the UK, 
it took 3 hours to get through the immigration queues.

I recall seeing signs saying something like:


  "Registered Travellers from [list of countries] can use the EU/UK lines."


I have another trip the the UK in a few months,
and I am really dreading the giant queue, especially after a 17 hour flight.

So I am looking up how to become a Registered Traveller.

It says:



Apply online for Registered Traveller membership. ...
You'll get a decision on your application within 10 working days. ...
If your application is accepted, the next time you travel to the UK you must go through the 'other passports' lane and fill in a landing card.
The immigration officer will check that you meet the criteria and tell you if you can become a member. ...



So does this mean that being accepted at point 2, isn't a real acceptance.
You get the real acceptance the first time you enter after applying, using the 'other passports' lane (i.e. the non-UK/EU line).
And then after that if you visit the UK again (assuming all successful), you get to use the EU/UK lane?

(I mostly just want to know if I am understanding it right. I think other things mean it just isn't financially worth it to me to become a registered traveller. I'ld need to pay for a Visa since I've not visited 4 times before)


Answer: Is it possible to use UK/EU lanes as a Registered Traveller the first time you enter the UK after applying?


Question: The bed in the hotel I am staying at has the rigidity of wood! It gave me a terrible night as I woke up every hour or so with loss circulation in my limbs. Even after spending the whole night in bed, I feel more tired than when I went to sleep!

The only trick I know is to sleep over the blanket, which I folded in two, but in a place where its 37C during the day, the blanket offers very little padding.

What else can be done to improve sleep on a hard bed?
