**Visiting your boyfriend every other weekend is not automatically prohibited.** The key question is whether you are genuinely visiting or effectively making the UK your home. UK visitor rules require you to leave after each visit and prohibit living there through frequent or successive visits. [UK visitor rules, V 4.2](https://www.gov.uk/guidance/immigration-rules/immigration-rules-appendix-v-visitor)

Officials assess the whole pattern: how often you visit, how long you stay, and your ties to your country of residence—which can be France, even though you are Brazilian. There is no blanket “six months in any twelve months” rule. On the facts you describe, short weekends alternating with your boyfriend’s visits to Paris look consistent with visiting while maintaining your home and studies in France. That is an assessment, not a guarantee of admission. [Home Office guidance, section 7.4](https://www.gov.uk/government/publications/visit-guidance/visit-caseworker-guidance-accessible--2#74-frequent-or-successive-visits-how-to-assess-if-an-applicant-is-making-the-uk-their-main-home-or-place-of-work-or-study)

To make your circumstances easy to demonstrate, I would carry:

- Your French student visa or residence permit, showing you can return to France.
- Proof of university enrolment and, ideally, your class timetable.
- Proof of your accommodation in Paris.
- Your return booking for that weekend.
- Evidence of funds, plus your boyfriend’s address and contact details.

These support the requirements to show your circumstances outside the UK, your intention to leave, and how you will fund your visit.

Be straightforward if questioned: you live and study in Paris, are visiting your boyfriend for the weekend, and return on Sunday. Your actual travel pattern should match that explanation.

**Under current rules, Brazilian passport holders normally need an electronic travel authorisation (ETA) for these visits rather than a visitor visa**, unless exempt. An ETA does not guarantee entry. [ETA eligibility](https://www.gov.uk/guidance/check-when-you-can-get-an-electronic-travel-authorisation-eta), [ETA overview](https://www.gov.uk/eta)

Finally, refusal of a visit because an officer is unconvinced you are a genuine visitor is **not, by itself, a lifetime ban**. It would, however, become relevant to future assessments.
