If you are willing to pay 8-10K+, have a master's degree, some dhoti bhaiyas will file EB2 for you from their company. these dhotis are doing this all over usa and i already saw some of my friends doing this and they are reliable. you need some network for that.  If you are STEM student and is in OPT currently, your OPT can be extended with less money. some of my friends are paying them on installments of  2K for the first month and 1K/month  thereafter.
