Hello guys!
we just got sponsor and applicant eligibility approval. Waiting for final decision and landing interview. Also I (applicant) got another message from CIC about "Invitation to obtain pre-landing services" . Does anybody knows what it is? Also, I am already in Canada as we have applied for inside canada. its confusing.
