USCIS has begun issuing RFE (requests for evidence) for updated medical examinations in connection with long-pending I-485 applications.
This is because is many medical exam forms are set to expire on May 31, 2014. From June 1, 2014 onwards, adjustment candidates should be aware that they might be requested to obtain and submit fresh medical exams to update their medical records on pending I-485.
The medical report I-693 is supposed to be valid only for one year but the USCIS has been issuing its policy annually to extend the medical report on file with the USCIS for I-485 applicant. But AILA has reported that the USCIS will cease such age-old policy.
