wonder how u get that admitted until stamp..its a LEAVE TO REMAIN until certain date..after that ur considered as illegal though u have a tps but might create problem during change of status after TPS.. admitted until stamp is generally given to those who have case pending in court( asylum) n they are given entry until their case is resolves in special case.. i would recomend to consut a good lawyer not Nepali type but one who handles refugee n asylum case
