Hi
Well, if they make decision after your marriage and before you inform them about your family status (marriage). You can just wait to land in by yourself. Once you have landed, sponsor your wife as spouse.
(just my opinion!)
Wrong Wrong Wrong. If he marries and his wife is not examined, then she is not a member of the family class and cannot be sponsored. Then he will be reported for misrepresentation. If he marries, and his application is being processed at Buffalo, then his updated application and her application must be sent to Buffalo. Then Buffalo will send the request for medical to her in India. If she passes, then there is going to be a real problem in getting her passport to Buffalo, as it is illegal to mail/courier passports in/out of India. If the OP was thinking he would wait until he receives his PR and "lands" then he can marry and sponsor his new wife.
