Congrats
@ratm_clone for receiving the ITA!
Please include ALL your work experiences in your full application, even it is not the NOC you are applying with.
For example, I applied with NOC 2174, but I also have several years experience in NOC 4011. For my EOI I mentioned NOC 2174, but for my full application, I mentioned both NOCs.
So you need to give ALL work experiences in the past 10 years, even if it is several different NOCs
No need for a LoE, but do have the original work reference letters for every position you held
You just need to show a Gift deed for the amount your parents are going to give you
Also include the transfer statement from your parents' account or cheque copy of the amount (if it was a cheque transfer)
Good luck with the next stage of your PNP application!
