加拿大公民，TN合同到期，想境内转成TD visa(as dependents），由于疫情原因，不想离境办理。请问如何自己在境内file or apply for TD visa? any line for thr application?
-File I-539 following the I_539 Instructions.
many thanks
所需材料是这些吗？
1. TN持有者的的护照，签证附件. also employment verification letter from the employer.
2. 结婚证明附件
3. TD人的护照附件
Also the TD applicant needs to provide his/her current TN status proof such as TN I-94, the paycheck stubs of the latest 3 months.
