Visas h1b – San Francisco To Hydrabad through Hong Kong with 15 hours of layover, should I submit a pre-arrival registration for a hotel stay in the HKG transit area?

I am an H1b visa holder and work in the USA. UU. Traveling to India through Hong Kong, where there is a 15h stopover. I have seen that there is a pre-arrival record that Indians must pass if they are leaving the HKG transit area. However, I plan to stay at a hotel called "Regal Airport Hotel" that is located within the HKG transit area.

Will I still have to go through the pre-arrival registration? What are my other options? However, I do not plan to leave the transit area.

Thanks for the help!

Mileage rate for LAX to HKG

It is necessary to check the route to know the mileage rate. If the fare exceeds the mileage, the routing will be applied or not. kindly advice

if the trip is LAX-EWR-JFK-HKG
LAX EWR travels on weekends with the rate from Monday to Friday and the date and time that the rule says
Allowed on Monday through you in each transport sector. Can we consider it as a day violation?
