回複：又新加了個問題，麻煩老師再看一樣吧～～

謝謝863211老師～～

我還有個問題，申請人的5年postdoc不是在同一個地方做的，輾轉過3個地方，請問這種情況下，是不是每個地方都需要chair或者老板sign這麽一個verification letter呢？
-You only need the last position Chair to write/sign the letter, but include all your postdoc experience (five years) in the letter such Dr.XXX has five year research experience in the field of XXX since he got his Ph.D in 2005. "He had worked in the XXX University for two years, then XXXX Univerity for 1 before come to Dept in 2009. Since he came to my Dept in December 2009, Dr. XXX has worked as a Research associate..."

或者是不是可以隻要找其中2個老板sign2份，保證時間大於3年就OK了？

謝謝～～
