Marrying for the purpose of receiving an immigration benefit is considered fraud and has severe consequences. (Case denial,being removed from the country, forever having a "Fraud" marker on your immigration record, etc.) Not to mention that entering into a marriage for anything other than love is a recipe for stress, heartache, abuse.... (In my opinion) I strongly urge you to practice patience in your immigration journey and do not try to take shortcuts. USCIS is really good at sniffing out these kinds of things.
