Hi,
If you want to create an Express Entry profile, firstly, you must receive transcripts from your university. Once you get them, you must obtain a positive ECA (Educational Credential Assessment) report which shows that you have equivalent education as per Canadian standard. Also, there is no such deadline to receive a WES report. Once you get a positive ECA and language proficiency score test , you can move ahead to submit an online profile. While creating profile, you need to fill all required information correctly with respect to age, education, work experience, Language ability and so on.
Hope, this understand!
