We have been in touch with many US immigration attorney's.  The main options are:
 
	 
 
	EB-5-  relatively slow and very expensive.  
 
	E-2- Cheaper but not an immigrant Visa.  3 year and must be renewed based on business performance.  Still need to figure out immigrant visa options. 
 
	EB-2 NIW- Cheaper and faster than EB-5.  Has education requirement and must propose activities (usually a business) that is in the "national Interest".
