Hi , I applied for Parents and grandparents sponsorship 2021 program through online portal.
Today I got a letter from CIC via email stating that i have some information missing on form IMM5406. The letter mentions that i can resubmit docs via email or mail. I also checked the online portal and it says application return and seems like i can resubmit through the portal as well. What should i do should i resubmit via email/mail or through portal? anybody in same boat? Sending through email as well as updating portal might cause confusion right?
