Pui,
You will need to provide this document with the scan of your transcript to InterExchange. Please email it directly to them.
Also, they are asking you for proof of 1-year of professional work experience in your field. You have an accounting degree, but I would call your field “business management” which is much wider. I can help you with this letter right now.
I will need to know:
· Your current employer’s official name
· The dates that you have worked there (starting date and ending date)
· Your current role
This is very simple but InterExchange must have it to satisfy American government requirements.
Also, have you given them a scanned document of your previous USA visa?
