in addition to wat moneywater said, u no u just took 2 risks there, late submition, and paying with a credit card thats almost expired, but no need to panic, your AOR will come within 2-3 months, pls don do this again, try to be fast with CIC cos they are slow, now u will go to that bank and apply for the credit card or master card extention, u just apply for 3 months extention,
2 incase of your nomination, if it expires before you get AOR, you mail there office, they will give you another 3 months nomination letter extention, the 2 has solution, u dont need to worry at all
