"Definitely yes! Immigration authorities can look at your text messages (and other electronic communications), but whether or not they do so is another story.
Please consider that there are a few reasons why immigration authorities might be interested in looking at your text messages:
They could be trying to gather evidence that you've committed a crime. For example, if you're texting someone about smuggling drugs across the border, that could be used as evidence against you.
They might be trying to collect intelligence about what you're up to. For example, if you're texting someone about plans to build a bomb, that could be used as intelligence against you.
They might just be trying to monitor your communications."
