You don't have to apply to a Province separately if you have an ITA. You just need to continue with your ITA and submit all the requested documents and make the payment for PR application. If you receive a nomination from a Province, then by accepting it you only boost your score by 600 points so that receiving ITA becomes easier. You already have an ITA so you do not need nominations now.Thanks Santosh . Could you please let me knwo teh process of applying to a province once we get ITA ?
