A signed offer letter from the employing entity with duties, salary, temporary period and title, plus written confirmation of the state licensing requirement and of who is responsible for obtaining it.
Ask for it in writing before resigning
The two documents that matter most are the offer letter and the licensing confirmation, and both come from the other side. The letter should be requested in draft so that the duty description can be reviewed before it is finalized, since a description written by an office manager rarely reads the way a professional classification needs it to read. The licensing confirmation should identify the specific board, the credential required, whether credential verification through a third party is needed, and the current processing time. If the practice cannot answer, the state board publishes its own requirements and the applicant can obtain them directly, which is slower but reliable, and it is better than travelling on an assumption.
Hypothetical example: A Canadian accountant is recruited to audit agricultural co-operatives for a United States firm. A first review should compare the signed offer, a detailed duty list, the applicant’s accounting credential, and the name of the entity that will pay wages. The record that settles an ambiguous role is usually the executed engagement or employment agreement, not a generic job advertisement. Put documents in that order, flag any mismatch in dates or supervisor, and ask the employer to correct the source record before a packet is assembled.
