回复：485 ref , have aquestion

问pijiang老师，485 ref 中写道: a currently dated letter or other evidence from your intended permanent employer that indicates your current position.....老板给出了一封信证明了现在工作（仍然在同一大学工作），所以就把老板信和体检表邮回去了。
-It is OK just to provide the employment verification letter (You should have asked the Dean or the Dept Chair to provide this letter). So, do not worry.
