previously it was possible but now rules are changed recently and you could not apply for oci before acquiring surrender certificate
Not BLS toronto it seems, I have appointment next week and am in same situation.
Oh boy. What a waste of time for the CGI , BLS and us. Why can’t they just create an integrated application that lets you surrender the passport and get OCI in one shot and one fee in one BLS appointment which you need to book at least two months ahead . I’m thinking of tweeting this idea to MEA but I know someone would have tried that already.
