Can I (as IMG) do an elective in PGY-3 in Mass (coming from NYC)?

So here's my dilemma.

I'm on J1 visa here in NYC, IMG PGY2 Psychiatry. I'm on restricted/provisional license in NY, as I am a IMG and can't get my full license until after PGY-3 (so PGY4).

I'm interested in doing en elective in Boston (Neuropsychiatry). The PD at one of the hospitals stated that the application is due end of PGY3, so it would be advisable to do elective early PGY3. But he said that in order to do an elective as a PGY3, I need a MA License.

So here's the issue, according...
