Hi Asivad,
A few more questions for you.
1). When you say explain something in the "letter of explanation" are you referring to the one letter of explanation which is optional and we are allowed to upload or you are referring to uploading a letter along with the area of concern lets say marriage certificate or employment documents. Which would mean if we have something additional to explain in multiple areas we would be uploading a letter each along with those documents or we lump all concerns in one letter and load it as the optional letter.
You can do it either way - have multiple sections in 1 letter of explanation where you highlight individual areas of concern OR have multiple LOEs which are uploaded in the respective section along with the other dcouments.
2). Also would you know if we are asked to upload educational documents for spouse if we have included education in the EE profile but have not claimed any points by saying no ECA performed. I'm not clear if I need to have these ready to be uploaded after ITA even if I didn't claim any points as I'm getting impression from some posts in the forum that if no points claimed, the system doesnot ask for the upload for spouse.
I'm not completely sure of this because I'm a single applicant but common sense dictates that if you haven't claimed points by saying no ECA done, asking for ECA is meaningless. I don't imagine CIC would ask you to upload ECA for the spouse. If they ask for diploma/degree to be uploaded, you can do that as-is except if they require translation.
