Resolve the discrepancy with the employer before presenting the documents as a consistent account.
Use the correct explanation
An outdated office address and a changed assignment are different situations. Preserve the actual terms and explain the discrepancy rather than choosing whichever address appears more convenient.
The employer letter should state the professional title, describe the planning duties in order of importance, name the qualification being relied on, give the salary, and state the intended period of employment and where the work will be performed. The support letter should state the listed profession by name, the discipline of the applicant's training, the duties in the United States, the identity and credentials of the professional the applicant supports, the duration of the engagement and the compensation. Ask the hospital's recruiter for a letter on letterhead that names the legal employing entity, states that the applicant is being engaged as a Registered Nurse under the USMCA, and describes the unit and duties in clinical terms. The employer must produce a letter that names the profession and describes the real duties, which often takes several drafts because human-resources staff write job descriptions for recruiting, not for immigration. Ask the employer to write, for each required element, a single sentence naming the record that addresses it, and to put those sentences at the front rather than leaving a reviewer to infer the mapping from a folder of attachments.
