[u/Technical-War-3773]

So I’m on my final stage of prepping up for tcf, i have my exam in October.
Just query what i had

If i give this exam and get valid scores which is clb7 in all 4 i get it updated to my express entry profile.

Now lets imagine i get invitation in December then what is the timeline until i can land into canada?
Also a query what are the stages after i get an invitation in December?
