What are the requirements for Egyptian residents to travel to Hong Kong for tourism?

Magdy, it may cost LE 280, but the final payment should be subject to the actual payment given by the embassy.
I don’t know what you mean for your second question. You mean the residence permit in Egypt? If yes, it is not required when you apply for HK tourist visa.
You need to provide those documents for HK tourist visa: copy of your passport, proof of your financial support, a completed application form, a passport-sized color photo, transportation and accommodation arrangement, and your travel itinerary.
