VAF2 Question 7.16

[tiger@tigress]

Myself and Hannah are eventually going to apply for our Fiancee visa in July this year. I am confident I can produce an application that meets all of the criteria and has all the information required.
However, in regard to Question 7.16.
Have you ever been refused entry to, deported from, or otherwise reuired to leave another country
Hannah has previously been refused entry into Hong Kong. At the time she was given no apparent reason. This is not on her current passport on her previous one.
Will this have any great significance in the result of the application?
Im really worried about it as I think it might be our only stumbling block

Always tell the truth....
