If local INS refuses, apply with the nearest district office. (search in INS website- field offices)
When you apply for interim EAD and the officer says it is refused, most people dont get it in writing.
Yes, if interim EAD is refused , get it in writing (have a letter typed ready which states that today's date is beyond 90 days from EAD/AP and local or district office commissioner refuses to give interim/emergency doc on such and such date)
If you have a lawyer, ask the lawyer to stand with you in the Q...
