TD permits study but not employment. A placement’s actual activities require assessment; academic or unpaid labels do not settle the work question.
Examine the host’s role and the tasks performed
Record supervision, hours, academic credit, duties and any compensation or allowance. Identify whether the host receives productive work and what the school requires. Have the arrangement reviewed before the start date. Do not assume the principal’s laboratory job or professional qualification authorizes the spouse’s placement.
Hypothetical example: A cartographer accepts a temporary professional assignment while the spouse plans to volunteer at a community arts program and a teenager wants a paid weekend job. First identify every family member's intended U.S. activity, status basis, age, and school or work objective. The review should produce separate answers for the principal and each dependent rather than one household assumption. TD classification may allow study, but it does not authorize employment. A volunteer role may still require careful review of its duties and whether it displaces paid work. Keep school admissions, relationship records, and any proposed activity description in the file. Sequence travel planning after the family status questions are settled. Trouble commonly begins when an employer's onboarding form is mistaken for work permission or when a paid allowance is described casually as volunteering. The principal's TN evidence does not convert a dependent's plan into authorized work.
Ask the school, host, or employer for a written description before travel. The answer should distinguish attendance, study, volunteering, and paid productive activity without relying on the family’s informal label.
