Scar tissue on the ear drum is usually caused by repeated ear infections. The scar tissue can lead to difficulty hearing and eventually ruptured ear drums. Surgery is one means of avoiding progressive hearing loss or ear drum rupture. No patients have reported taking Scar tissue removal (eardrum).
USCIS normally responds to RFE's within 60 days, however they do not have processing times on how long it takes them to respond. It can be longer than that. I would call the USCIS number: 1 (800) 375-5283 and submit a service request, if you do not hear from them soon.
You must mail or hand-deliver one copy to the other party the day that you filed the Application and Affidavit of Default you must wait 10 court days. If the other party still does not file a written Response or Answer in 10 court days, you may be able to request a default hearing date. You can set a default hearing on the internet at http://www.superiorcourt.maricopa.gov/ezCourtForms/, or by calling 602-372-3332.
