Have you checked the prices in the US? Will your current employer support these courses or is this all out-of-pocket for yourself? You could also seek out a Company that is offering the course internally and offer to tag along at a prorated cost. My 2 cents.
Perhaps try nd find an online correspondence teaching source that may help you in attaining this without the cost of Boarding and school fees and food and the rest.Try attaining this result through some very spoof proof websites which removes the heavy handling of fees by middleman and getting the modules done online!! but beware of such websites ensure they have valid USSIC codes.
