Your organization can file an EB-1C petition at any time. You may file a concurrent Form I-485 so long package is filed prior to the expiration of your current nonimmigrant stay. Timing of the filing is important so you can continue working with interruption. You can find more information on EB-1C at http://myattorneyusa.com/eb1c-visa-category-multinational-managers-and-executives.
