After 5 months ,I realized that the EAD card contains wrong information. I mistakenly entered wrong information on my I-765 form . My first name comprises of two name and I have last name.MY first name is Ravi kumar and last name is pradeep. I have no middle name on my passport but in i-765 I entered my first name as Ravi and middle name as Kumar and last name as Pradeep. Should I contact USCIS about this mistake I made as it has been 5 months i have received my EAD Card. Will it affect my work authorization eligibility Please help.looking for your experienced advices.
