I saw your old post about using PTO cover EAD gap, you said Get a letter from them if possible, stating that they haven't paid you any salary during the EAD gap. You may need it in future if USCIS issues any RFE about it. Just want to know , Could I use check stub to prove that I didn't work on EAD gap . Usually, there is information showing that that pay is from sick pay, vacation .
