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 may postpone your service for up to six months from your reporting date. You must have your juror ID number in order to access your records. If it is more convenient for you to serve by appearing up to two weeks before or even up to two weeks after the reporting date on your Summons for Jury Service. To do so just bring your original jury summons with you to your service location on the days listed below.
