Van der Vaart, 33, joined Betis on a free transfer last summer after his contract at Bundesliga side Hamburg expired but has since featured just nine times for the La Liga club, recording one assist.
The 109-times capped Netherlands international, whose current deal expires in 2017, is now expected to leave Los Verdiblancos in the near future and was linked with a move to the Chinese Super League just last week [h/t Bild].
However, Marca claims that the former Ajax and Tottenham Hotspur midfielder is instead weighing up an opportunity to join MLS as a Designated Player, with Sporting Kansas City, Columbus Crew SC and the New York Red Bulls all named as potential destinations.
This would not be the first time that Van der Vaart has been talks about a potential stateside switch, as the skilful Dutchman held advanced discussions with Sporting KC before leaving Hamburg last summer.
Club officials travelled across the Atlantic several times to meet with the two-time World Cup veteran, but the deal collapsed in the end after the two sides failed to reach an agreement over financial terms.
"No disrespect to him, but it doesn't make sense for the kind of numbers we're talking.”
Now nearly 11 months later, it sounds like Van der Vaart may well be ready to lower his demands.
