You must provide original evidence of identification and work authorization no later than your third day of employment. We would, however, appreciate it if you could bring these documents with you on your first day so that we may complete the I-9 form in its entirety. Attached you will find a list of acceptable documents to be used for both identification and work authorization purposes.

BankUnited offers excellent opportunities for a challenging and rewarding career and we look forward to working with you. We believe you will make an outstanding addition to the BankUnited team.
