About submit extra Recommendation Letter (4th LOR)

Hey folks,

Is there anyone who submitted the 4th LOR to make your case stronger and also for the backup?
If so, did you choose the criteria for the letter? or just uploaded in the evidence file without providing the criteria?

You can only add any other references within you application (3 page evidence). LOR must be 3 because you will be provided with only 3 options when you are filling your TN application

I think the appropriate term for a 4th LOR is a letter of support.

You can get someone to write a letter of support which you can attach as one of the ten pieces of evidence.
