hi 121,
since yu hv got re med request means, visa officer is satisfied dat yur relationship is genuine based on ur proofs + interview. yu hv also passed background checks like criminality and admissiblity, but he cnt issue yu a visa with yur expired medical or about to expire (means yu cnt b able to land before it expires), so he requested for re meds. now yu hv sent them yur re meds but the medical is still with the Regional Medical Officer who will reassess the medical, make a report and forward it to visa officer, visa officer then will make a decision. status will turn to DM. then ppr n visa. RMO usually takes 2 months n few days to frwrd it to visa officer. hope this helps. gud luck.
this is from cic site.
The re-med process applies only to cases where a final decision is pending due to either:
the expiration of a medical certificate; or,
when the validity of the medical certificate is about to expire and the applicant is unable to land before it expires.
The process does not apply to applicants who are inadmissible on health grounds since inadmissible ‘M' profiles do not expire.
