No blanket permission follows from the initial role. The actual activity must remain consistent with the applicable authorization and requirements.
Assess the proposed addition
Identify what work changes rather than describing every amendment as administrative. An unchanged project name does not establish that new responsibilities fit the listed profession.
An offer that names the profession, the duties, the supervisor, the location, and the compensation, subject to a clearance, reads differently from one that reserves the right to withdraw for any reason. An employer letter that spends its length on salary, benefits and relocation while describing duties in a sentence leaves the central question unanswered. Often other official institutional records show the credential and the date it was awarded, and counsel can assess whether those satisfy the credential the listing names for the intended profession. Start by naming the exact USMCA profession, then compare its stated education, licence, and experience criteria with the actual foreign award. TN analysis starts with eligible Canadian or Mexican citizenship, a listed professional occupation, the required qualifications, and a genuine temporary engagement for a US employer. Ask the employer to title the position Computer Systems Analyst and to describe the requirements-gathering, design and specification duties in the support letter, with coding mentioned as a component. The listed degree or documented five-year experience route still matters, together with citizenship, temporary entry and the actual employment structure.
