I apologize in advance if this post is in the wrong place. I will be in the US for some of the March window and I'd like to watch the CONCACAF WCQ games. I assume these games will not be on tv. Is there an online service I can subscribe to in the short term?
Why would you believe that? Games are shown in the US. Many of them will be shown on TUDN (in Spanish). Any particular game you are concerned about?
11 out of 12 matches should be available in English on Paramount+. One match, USA-Panama, will instead be televised by either ESPN or FS1.
https://www.paramountplus.com/shows/concacaf-qualifiers-road-to-qatar/ is the link. It costs $4.99 for one month.
better yet, find a local soccer bar (ideally US centric, unless you're rooting for the other teams, in which case you shouldn't have any problem finding a bar for those too).
