State licensure application costs, credentialing and primary source verification through the institution, and possibly examination or documentation requirements set by the licensing board. These are separate from any immigration process and their amounts should be confirmed directly with each body.
Budget the licensing track separately
Licensing and hospital credentialing usually involve their own applications, verifications of training, and document requests from institutions that may be in another country. Departments sometimes cover part of this and sometimes do not, so ask early who pays and what the institution handles internally. Treating these as one budget with the immigration matter tends to hide the larger and slower of the two.
Ask each body for its current published fee rather than relying on a figure a colleague quoted from a previous year, and ask whether the fee applies per application or per verification requested. Credential verification services often charge separately for each institution contacted, so a physician trained in two countries can face a larger bill than one trained in a single system. Hypothetical example: a residency programme administrator handling several international recruits keeps one institutional budget line for credentialing and none at all for an individual's immigration costs, and the recruits discover the gap only after accepting.
Ask in writing, before accepting, which of these costs the institution pays directly, which it reimburses, and which it does not touch. Reimbursement after the fact still requires the money up front.
