Can anyone recommend a lawyer to help a Sri Lankan bank register as a money transmitter in New York (and later other US states)?

Two names I can suggest (please do your own due diligence):

• Perkins Coie (http://www.perkinscoie.com/)
• Morrison Foerster - specifically Barbara Mendelson - http://www.mofo.com/barbara-mend...

You can also look up Adam Atlas - albeit he is based out of Canada, but don't discount that (See http://www.adamatlas.com/)
