Dear K. Somruthai / K. Chatchai
US just found out that Patton's written authorization contains a small error on the last paragraph of the letter. The date being required to be inserted in the template (expiration of the written authorization) is three years from the letter date.
Would you please help revise the letter from This written authorization will expire in three years on 2/12/2017" to be
“This written authorization will be expired after three years from the letter date ”
