Applicants/Sponsors with a large difference in ages The rules do not state that the applicant and sponsor must be within a certain age differential, but if there is a disproportionate age difference (for example, more than 25 - 30 years), additional care needs to be taken when applying for a visa
as for meeting only once, well i would have thought it depends on the amount of evidence you have, or lack of evidence that could effect your visa app and how long you have known each other..
