Certainly, yes! I am sorry if I didn't make that clear. Not only should you actually be in love/want to marry to avoid fraud but also for your own well-being.

The United States has an adult population of 258.3 million, so it's likely you'd find someone to fall in love with if you're really looking.

I have some experience here, I have a double digit amount of family members who came to the US to marry into my family, including my brother-in-law. With one exception they are all very happy marriages, the longest lasting 3 decades. There were some who were definitely were looking to marry Americans to immigrate, but the relationship is still real.

Americans are a great bunch. Contrary to popular (outsider) view, I think american family bond is very strong.
