by the way, call them everyday or every two day

Since your PD is so ealier,and your case is still there.
The Phone call picker also fell strange about that sicne the memo is there now. There is no block for your case approval. The nomally will show your case to their supervisor since your case's staying there is abnormal. So teh supervisor will make a decision on your case, either approve immidiately or assign to a officer quickly for a quick relative detailed review. So that is good news! you will be approved very soon if you arevonly stucked on NC.
