HI, i am arranging visas for 7 people travelling to China for a business trip.

Do they all need to sign the forms? I notice there is an option to sign on behalf - can i simply sign for them as i have completed the forms?

Or does the embassy accept scanned copies of the application form?

Also - i have had differing information regarding the invitation letter - does the invitees passport number have to be on the letter? it does not say this on the embassy website, but a travel agent has told me it does

cheers
Sarah
