if you ask me whether or not you should come to US, I will say DO NOT COME. That's the same advice I have given and will give to my family members. It is very hard (read almost impossible) to get H1B or green card (GC) sponsorship even with US BSN degree for F1 students. The hardest challenge in US is the limitations that come with being on student visa than money and difficulty of the course itself in my opinion. If you do not have any problem marrying anyone (often Kaley, gorey, Mexican, Pakistani etc) like other Nepalese (mostly girls) to just get your green card than you will be fine in US. The best routes are getting a DV or honestly marrying a person with H1B, GC or US citizenship.
