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.
How long must a permit-holder wait before making an appointment for a driving test? Once you earn your learner's permit, you may be forced to wait an allotted amount of time before you can take your driving test. Some states allow you to schedule an appointment in advance, but you must usually wait 120 to 180 days before taking the test. This delay varies by state, and you should consult your local department of motor vehicles for specific requirements and instructions.
