Basically, provide the wedding certificate, lots of older pictures of when you were dating in the past before wedding, salary statment, rental agreement, work contract etc, give as much information/evidence as possible, that is what my friend did.An application for admission of a dependant may be favourably considered if:
there is reasonable proof of a genuine relationship between the applicant and the sponsor;
there is no known record to the detriment of the applicant; and
the sponsor is able to support the dependant's living at a standard well above the subsistence level and provide him/her with suitable accommodation in the HKSAR.
