Em teoria, sim. Ela pode receber um escrutínio maior do que a média quando voltar aos EUA. Se ela tiver planos específicos para uma estadia curta e um voo já reservado para levá-la para fora dos EUA no final da estadia, de preferência para um destino fora da América do Norte, ela provavelmente ficará bem. Ainda assim, há uma chance de que ela possa ser impedida de entrar.
Ela também pode enviar um pedido de mudança de status buscando o status de visitante B-2. Isso é bem mais caro (US $ 370), mas essencialmente garante que ela poderá se juntar à família nas férias e participar do casamento, pois esses pedidos levam semanas ou meses para decidir, então não há chance de que isso seja negado antes que ela planeje para sair de qualquer maneira.
Devo chamar a atenção para o avisos oferecidos em várias comentários :
I disagree with the filing change of status part. Since the change in policy last month, a denial of a change of status leads to being immediately put in removal proceedings. Even if by the time this happens she’s already left the USA, on her record it will likely be annotated that she was in removal proceedings. That will likely lead to massive problems at her next entry. Applying for change of status or extension now is not recommended unless under absolutely necessary. – Musonius Rufus
@MusoniusRufus can she not withdraw the application if she leaves before it is decided? – phoog
You are aware that USCIS and ICE are not fully integrated. Also from my own experience I know one can file additional paperwork for a petition and it can be sitting somewhere with them while the original petition is adjudicated without them reconciling the two. So yes she could file to withdraw but by the time they enter that into their system the original petition could be adjudicated and her put in removal proceedings with them not realizing she had already withdrawn it. Of course she can go on and have it corrected but will she even know until she tries to come to the USA next time? – Musonius Rufus
USCIS & ICE are notoriously incompetent and siloed and can be doing things related to the same person without talking to each other or updating each other about developments. I would not risk it. – Musonius Rufus
