Dear pjiang:
thanks for your answer.
i read the 可憐天下父母心, and use the link there
http://www.immihelp.com/immigrant-visa/cspa-calculator/
* 答案的準確性不再老師的掌控之下
my question is which values are input into the above table for calculation or how to caluclate the extended days? do we need to use priorid date, how about the 準確性 in above calculation.
by the way , in 可憐天下父母心: 比如說,王五同學的 EB-2 PERM 申請於 1/2005,並於 9/2007 獲批。隨即交了 I-140, ND 為 10/15/2007, AD 為 12/18/2007.
what are the ND and AD? is seems in my I140 aproval form, there are only, PD, receipt day and notice date. so something must be different.
thanks for your help. please solve my confusion. many thanks!
