Starting Sept. 12, 2011, the USCIS will change their document delivery practice. If an applicant is represented by legal counsel, the USCIS will send the original receipt notice to the applicant's address. The attorney will receive a copy of the receipt notice. Prior to this date, the USCIS would mail the original notices to the attorney on record.
The USCIS states that they are doing this to ensure that the applicant receives important docs such as the I-94 arrival/departure record. Based on my experience with applicants and petitioners constantly moving around, their preference is that the original be sent to the attorney. So this change may not be beneficial for those types of individuals. Hopefully this change won't be too problematic. We'll see.
