Our Philadelphia immigration lawyers represent researchers at prestigious Universities and Hospitals throughout the United States. When filing EB-1B outstanding researcher petitions and EB-1A extraordinary ability alien petitions we generally utilize the premium processing service and wait for an approval prior to filing the I-485 Green Card Application. This strategy ensures that time and money will not be wasted filing the I-485 Green Card Application in the event the I-140 Petition is not approved. We successfully processed an EB-1B outstanding researcher petition for a researcher performing statistical analysis of disease outcome research for one of the most prominent children’s hospitals in the United States. Following approval of the I-140 Petition, we filed the I-485 green card application which was approved by USCIS in a very short time period.
