My cousin that lives in the UK is the grandson of my father's uncle. Basically, my father and my cousin are very close friends, and me being my father's son, my cousin wants to invite me to the UK.
Can I use our extended family relationship to get a family-based visa? I have all the papers that prove we're related.
Should I instead apply for a standard visitor visa with my cousin giving me a formal invitation? I plan to initially go for a 15 day trip, then go on a longer visit later. If the first visa doesn't allow multiple entries, can I invalidate (cancel) the visa once I return home and apply for a new, longer visa?
