Do we have to call to find out the interview date? Does anywhere in package 4 show the interview date? By the way, my husband just the P4, it seems that he has a hard time to find out the interview date. Could anyone give a hint? Thanks! p-4 is the interview letter,it will have the date on it for the interview. But where should I look at? on which paper? Since I don't have the orienginal document with me, I checked the embassy GuangZhou website, in their sample document, I don't the date showing anywhere either. Inside the P4 should be a letter letting you know that an interview has been scheduled. Look at the Bottom left corner There should be a time, date and Location.
