An application for a replacement EAD is filed if a card has been lost, stolen, or mutilated, or when the previously issued card contains erroneous information, such as a misspelled name or name change. If an application for a replacement EAD is approved, the replacement EAD will have the same dates and category as the EAD that was lost, stolen, etc.
Persons applying for replacement documents can present the receipt for the I-765 as evidence of employment eligibility but must produce a valid card within 90 days of showing the receipt."
