Thanks for the link, one thing which I think it is not correct on this link, it is stated that if the spouse has a disease which is medically inadmissable due to excessive demand the immirgration file could still be accepted and not refused on excessive demand grounds if the spouse gave the problem and he/she is not the main applicant, I do not think that this is quite right as I know a case which has been rejected when the wife has been affected by cancer after the application and husband was the main applicant??!!
Thanks
