Hi Asivad Anac,
I recently landed a new job after applying for PR( FSW inland ) through express entry. Do I need to notify CIC about this?
If you change your job after submitting your post ITA application, there is no necessity to inform CIC about it unless your ITA was contingent on that job (LMIA job and some PNPs) or you're changing cities/countries and you need to inform CIC about change in address. If you change your job before getting an ITA, you might want to inform CIC about it if you want to include the current job in your application in order to get CRS points or for program eligibility purposes.
And another question, can I update my proof of funds situation after submitting the application as I was not able to show the required funds before?
Normally, one cannot update this after submitting their post ITA application. If you still want to do it, you can try sending in a CSE requesting them to add this information to your application. It's completely on the officer's discretion if they would acquiesce to such requests or not. Definitely worth a try though.
Thanks for your help!
