They don't own a property, but me and my wife jointly own a property in which they live. my mom is a housewife and dad is retired.
I m not sure how to prove ties to home county as they do not have a job and they earn from their Fd's and retirment savings and my father take private tutions.
Sorry missed that it said in you wife’s name. Unfortunately they have a pretty weak application. You can certainly try to apply but you will likely have to wait until you have your NOA to apply for supervisa if you meet LICO.
