Dear Khun Jariyaporn,
This is just a gentle reminder to you that we had distributed FATCA declaration letter to your goodselves around Mid-August 2015. (three months ago) However we still have not received the form back from you.
A gentle reminder to you that you are required to fill up the declaration form and return it to us at your earliest convenience but no later than June 2016.
Should you need any further assistance, please feel free to contact me ka.
