Thank u so much for ur helpI am so sorry to hear that.
I filled it myself. I sent them the following document:
-Amendment Letter- I wrote a letter to the immigration officer stating my issue and why I wanted the changes.
-Amendment Form- I filled in all the details and in the information to be amended section, I chose "Other changes" and in the reasons for the amendment, I specified my reason.
-Passport copy
-My work permit
Hope this helps!!
Note: There is no need to stress too much as the documents will be verified and if they need something else they will let you know.
Did u fill the full information in part B information need to be amended? Like name surname all the personal detail again
