I-129F awaiting approval, can fiancee visit me with existing visitor's visa?

[Abstract 0]

Hi, new member here. I tried searching on the net for my specific inquiry w/o any luck, but it seems like this forum is where I might find my answer.

My fiancee and I already received confirmation that the USCIS received our I-129F petition, so we are just awaiting approval. She is currently studying in Canada (actually waiting for school to start) and has a U.S. visitor's visa that is yet to expire, can she still come in to the U.S. with her visitor's visa? I've heard rumors that once you guys turn in the forms, your fiance(e) can/should not come into the U.S. in the meantime, because of either doubt of her immigration intentions or a possible impact/delay in the progress of the I-129F approval.

My logic tells me that if her visitor's visa is still valid and she has proof (flight back, school enrollment) that she will leave the U.S. in accordance with the rules of the visa, then she should be able to enter and not have any affect on the I-129F.

I tried calling the NCSC that claims to have live help, but all I get is a recording that doesn't seem to have a selection for it. And I'm definitely calling within their stated business hours. It's so fustrating to find some definitive help in these matters.

She can visit the US but there is no guarantee that she will be allowed entry. This is always the case, but the I-129F filing establishes immigrant intent which must be overcome at the POE. In other words, the burden of proof that she will leave is higher now.

That being said, being currently enrolled in school is a pretty good indicator of intent to go back, so she probably stands a good shot of being admitted.

as long as she brings proof that she will return to canada and it is before her visa expires , she can go visit you ,

I visited my husband ( back then fiance ) without any problems while the I 129 was in process ,

( I had a visitor visa too , so as long as she follows the regulations she can visit without a problem )
