I had applied for a PR under the RNIP .My wife and the kids I had put them as not accompanying me to Canada reason being they will follow after I had settled but now I had received email requesting them to do medicals with their UCI and application numbers given. I had only paid my application fees for me as the main applicant. I had done an upfront medical myself .I don't understand how the process works and I didn't receive an email requesting the medicals .Last week I received an email instruct me to pay for biometrics which I did. I only paid for me the main applicant.
