This is the situations now. Sent TPS re-registration application along with Travel document request two weeks ago, also sent check for Re registration and Travel documents but requested fee waiver for EAD (Work Authorization) based on low income. Still have not received any information from USCIS nor money has been withdrawn from the account. Now the question is if they did not approve the fee waiver, I understand they'll send back the application requesting correct fee. What if they send it late and I could not manage to send it back to USCIS before DEC 24-2016 deadline? Any suggestion will be appreciated.
