非常感谢老师的帮助，您上两次的回答对我们非常有帮助， 所以又来请教。
递交完行政审查要求的简历之后，我们被要求将体检报告、加拿大警方证明和护照及指导信交给指定的中信银行。 这种情况是否还会被要求去领事馆面签？
-Yes.
从提交这些材料到得到签证需要多长时间？
-Hard to say, depends on how busy the US Consulate is.
非常感谢老师的耐心帮助。 下面是我孩子的问题，我帮助他转发给您。
你好8老师， 谢谢你的回答。
我是一片片叶子的儿子。我现在在加拿大工作不方便回国去办签证， 想等父母办完再办理。
想问：
1. 把护照交给领事处之后，
-You need to indicate it in DS 260 that you want to get the immigrant visa in the US Consulate in Canada and then, contact NVC to make sure they will transfer your case to the US COnsulate in Canada.
签证大概需要多久才能拿到呢？
-Hard too say, depends onn how busy the US Consulate is.
2. 如果我父母先拿到签证之后，我能否把我的案子转到加拿大领事处呢
-Yes, see above. But you only can do it after your parent (primary beneficiary) enters US using the immigrant visa (this is the follow to join benefits).
我母亲是主申请人。这样会对他们有什么影响呢？
-No impact.
-Yes.
这个过程大概是怎么样一个流程呢
- After your parent enters US to become a green card holder, you need to contact NVC to express that you want to apply for the immigrant visa by following to join in the US Consulate General Montreal in Canada. Explain why you need to apply for the immigrant visa inn Canada, not in China.
Then, NVC will send you the instructions including the invoice for the payment, required documents, etc. Then, you just follow the instructions to pay the fee, file DS 260, and provide the required documents such as the copy of your birth certificate, I-693 physical exam report, I-864 Affidavit of Support with the support documents, the proof of your legal stay in Canada, the copy of your parent's green card or the endorsed immigrant visa page (i.e., stamped the immigrant visa by the officer at the port of entry when your parent enters US).
谢谢老师！
