I think they can.But it depends whether nursing school from nepal can suppy the document which

 needs to get license.I guess that part is quite difficult coz some board of nursing shows lack of  enough

practical hrs for Psychiatric nursing and some for pediatric nursing.If u get lucky to make documents which

board of nursing need,u'll get eligibilty within 3-4 months.

By the way anybdy has done nursing from biratnagar Nursing college?
