Have you already applied for green card? The application allows you to apply for travel document and EAD for free (apart from application fees itself). Processing times are expected to be long at this time. I applied for travel document in November last year but since all ASC offices are closed and they cannot get biometrics appointments done, it is taking a long time. You can also visit field offices for emergency travel document.

If not you should ask the immigration attorney that you are working with.
