Dont worry saku, Have your received a receipt from USCIS? I dont know where is your service center? Check the service center and check the processing date for your application through the uscis website. They should should sent you a notice or something stating that your application is processed or not? Have you moved recently or is the address that you applied is different then where you live rite now? There are many things that could affect your process. I would say you can call the costumer service of USCIS and inquire about it. Again dont worry, everything would be aight. and good luck..
