Is it possible for my husband to accompany me on a study visa in the UK for a Master's or PhD?

In the UK, dependents are generally allowed only for students enrolled in PhD/doctoral programs or research-based postgraduate programs (such as certain Master’s by Research courses) that are at least 9 months long. Students pursuing taught Master’s programs or bachelor’s degrees are usually not permitted to bring dependents during their studies under the current rules. So, if you plan to pursue a research-based master’s or a PhD program, your husband may be eligible to accompany you on a dependent visa. Otherwise, if he wishes to study in the UK as well, he would typically need to apply independently to a university and obtain his own student visa.
