Can I apply for a new Temporary Resident Permit if my first one is refused?

Yes, a TRP refusal doesn't generally bar a future application — there's no fixed waiting period the way there is for some other immigration decisions, and someone can apply again if their circumstances or the strength of their submission have genuinely changed. Simply reapplying with the same information and reasoning that didn't succeed the first time, however, is unlikely to produce a different result.

What tends to matter on a second attempt is addressing whatever specifically led to the refusal — whether that was an unconvincing justification for the trip, insufficient evidence, concerns about risk that weren't adequately addressed, or something else the refusal reasons pointed to. A stronger, more complete application that directly responds to the earlier concerns has a real chance; one that simply repeats the original request usually doesn't.

Because refusal reasons, where provided, are the clearest guide to what needs to improve, it's worth requesting and carefully reviewing them before deciding how or whether to reapply, and getting legal advice to build a genuinely stronger submission rather than resubmitting the same package and hoping for a different outcome.
