我现在H-1B已经批准，有approval notice.我太太现在是OPT，想等她在OPT结束时转成
H4身份。
请看下面的说明A：需要我当初申请H-1B时的I-129表。我现在H-1B已经批准，我有批准时
的receipt,请问这东西还是必须的吗？
多谢。
7. Dependents of an H, Temporary Worker
If you are filing for an extension/change of status as the dependent of an employee who is an H temporary worker, this application must be submitted with:
A. Form I-129 filed for that employee or a copy of the filing receipt noting that the petition is pending with USCIS;
B. A copy of the employee's Form I-94 or approval notice showing that he or she has already been granted status to the period requested on your application; and
C. Evidence of relationship (example: birth or marriage certificate).
NOTE: An employer should file Form I-129 to request an extension/change to H status for an employee or prospective employee. Dependents of such employees should file for an extension/change of status on this form, not on Form I-129.
