"Filing Form I-539 separately from the principal and the principal's case is approved: If the principal's Form I-129 (which included a request for change of status or extension of stay) has already been approved, file Form I-539 with the service center which approved the principal's I-129 petition. Include a copy of the Form I-129 approval notice to show the approved Form I-129 location."
"所以我觉得王二应该把I-539递到批准老婆I-129的NSC,而不是按照地址寄去CSC 或者VSC。"
