She should consider entering the arts competition of the Museo de Arte Moderno. It's open to Dominicans living abroad too. The only thing that could stop this is not having a cédula. If she does, the competition for recognition is less than in many art museums in North America. Once seleted by the museum's jury, that will help getting more exposure for her art, plus could give an advantage for exposures in North America since that will be in her resume and/or website.
If she doesn't have dual citizenship, she should apply for it this year and will be able to enter the next Dominican arts competition in 2025 (unless she is able to get everything done before the end date of entering the competition, because once the Dominican citizenship is claimed via jus sanguini, she gets a cédula and that is what is needed). If she already has one, then...

PS. Keep in mind that any works of art that wins will become property of the Dominican government, but all recognitions is given to the artist and it will be displayed at the Museo de Arte Moderno for at least 4 months, could be longer or even permanent. Up to three works of art per artist can be entered in one competition. She will also not be able to use the same work of art for any other arts competition in the DR or elsewhere if it wins the DR competition. Even if not picked as a winner, she will get a certificate of participation which is better than an obscured artist with nothing except her art for things such as sales of the arts, etc.
