How the Standard Visitor visa works, what the application has to show, and the mistakes that most often lead to a refusal.
For most Nepali families in the UK, getting parents over for a few months - for a graduation, a new grandchild, or simply a visit - means a Standard Visitor visa. The rules are not complicated, but refusals are common and almost always come down to how the application is evidenced rather than whether the visit is genuine.
On a visitor visa your parents can sightsee, stay with family, attend a graduation or wedding, do a short recreational course, receive private medical treatment, and carry out certain limited business activities. They cannot work (paid or unpaid), claim public funds, marry or register a civil partnership, or use repeated visits to effectively live in the UK.
That last point matters. Back-to-back long visits with only short gaps outside the UK are a common reason for refusal at the application stage and for questioning on arrival.
The caseworker is deciding one thing: that your parents are genuine visitors who will leave at the end of the visit and can support themselves while here. Build the application around that:
There is generally no right of appeal against a visit visa refusal - you normally have to apply again and fix the weaknesses. That makes it worth getting the first application right, and worth reading the refusal notice carefully if one comes.
Visitors are not covered by the NHS in the way residents are, and can be charged for hospital treatment. Travel insurance with medical cover is strongly advisable, particularly for older parents or anyone with an existing condition - and buy it before travel, not after arrival.
Agents in Nepal who offer “guaranteed” visas, or who prepare documents on your parents’ behalf without showing you what was submitted, are a real risk. False or inflated documents lead to refusal and can trigger a multi-year ban on future UK applications. Everything submitted must be genuine and must match what your parents can explain in their own words.
