Thanks jjr_90
letter of registration - I am preparing a Letter of Explanation informing why I need to extend my study permit and attaching a Letter from the College with the possible graduation date, amount remaining to pay for tuition and textbook;
possible graduation date - I will request on the College for a letter with this date and the amount remaining to pay;
transcript - that's something that I didn't thought, and thanks for sharing, I am going to attach an unofficial transcript up to date;
tuition fee receipts including past and current semesters - another thing that I didn't thought before, I am going to attach some information about it;
banking statements downloaded from online banking - besides that my manager of my bank will give me a letter informing how much money I have on my checking account and saving account, everything covers all expenses that I will have to finish my studies;
passport all pages scanned - I have a new passport, I am thinking to scan the pages from the old one and the new one, but I have to think how to demonstrate that in a logic way to avoid to be confusing;
financial support letter from my parents - did you attached any financial document from you parents, sucj as bank statements?
Thanks for your help and attention.
