I would like to get some information on PCL Nursing Evaluation in US.

What is the process to get to RN license if you have done PCL nursing and have RN license in Nepal but does have any experiences. If anyone knew what would be the better approach to get RN in US after coming in US? what would be the criteria to be eligible to sit on NCLEX exam if you only have PCL Nursing in Nepal? Is it better to join BSN or we could have some hours to be eligible to be in NCLEX exam? can we be eligible to evaluate our PCL course from Nepal in CGFNS?
Please ..any suggestion would be appreciate and helpful..

Thanks
