麻烦你，八老师，
正在填写 I-29，
本人现用TN工作，I-140 刚刚寄出三星期。HR告知支票已经CHARGE 了。但不知道什么时候才能拿到RECEIPT NUMBER。想请教八老师， 这样的情况这么填写 PART 4.
7. Have you ever filed an immigrant petition for any beneficiary in this petition?
选YES， how many 填 1.
在PART 9 中填写，
XXX company has filed an immigrant petition for Mr./Ms. XXX. The Form I-140 of Mr. XXX's petition has been developed and received by USCIS on (date). The receipt number of Form I-140 has not been received.
不知道可不可以？还是必须等收到receipt number 再 file I-129?
谢谢
