The foreign national spouse may file an application for work authorization form I-765 along with the petition. In most instances, they can also file for a US travel document using form I-131. You must read the instructions of every form to be able to properly fill the forms. You must accurately calculate the filing fees. I recommend you issue a separate check for every form and not combine them. Please remember to issue a separate check for biometrics fee of $80 if appropriate.
