Visa requirements are different according to each country. Visitors to Hong Kong must hold a passport that is valid for at least six months before the planned departure date to Hong Kong. Visitors from most countries are not required to obtain visas and can stay for periods varying from 7 days to 180 days, depending on nationality.
Please check the web site of the Hong Kong Immigration Department and the Chinese embassy or consulate to find out whether you need to apply for an entry visa to Hong Kong.
Letter of Invitation
As part of the visa application process, you may be required to include a visa support letter. To request a visa support letter, register for the conference and then email your request email@example.com, and include
- Your name as it appears on your passport
- Your current postal mailing address
- The name of the conference you wish to attend (“ACM SIGCOMM 2013”)
- Your Registration Confirmation Number
- If you have any papers accepted for the conference, please provide the title and indicate whether you are the “sole author” or a “co-author”
Visa support letters are answered in the order they are received. You will receive a PDF letter by email within the next 4-5 business days. Please note we do not fax visa support letters. The PDF serves as a signed electronic version of the original letter which will be mailed to your current mailing address. If you do not receive the letter by post mail on time for your visa appointment, please print out your PDF letter and take it with you.
Please note that Letter of Invitation will only be sent to participants who have registered and paid for the Conference. Should participants withdraw from the conference after the issue of Letter of Invitation, the consulate will be notified of the withdrawal accordingly.Contact the Registration Chair
