The implementation of the ESTA program will allow DHS to eliminate the requirement
that VWP travelers complete an I-94W prior to being admitted to the United States. We
are currently in a transition period, but anticipate that the paper form will be completely
replaced in the coming months. Until carriers are capable of receiving and validating
messages pertaining to the traveler’s ESTA status as part of the traveler’s boarding status,
travelers will still be required to complete the paper Form I-94W and present it to CBP.
