ma yeha sarkari thau ma kaam garchu jaha bata kahiely kahi citizenship nabhaako ley kaam gareko claim garyo bhaney inquiry submit garnu parney huncha INS ma. But we just do that inquiry for the period entered by the user, to check if that is in valid EAD time frame or not.
I can not guarantee other firms do the similar inquiry but when you provide the timeline, most likely it is automated process. Fetch the duration from form, send inquiry for the validity .
So I totally agree with what STUPIDA said .
