Self sponsorship vs relative or spouse sponsorship

[Annie065]

Good day, it a pleasure to be a part of this platform so my question is I went for my interview in oct and I work I got a letter from my employer so b4 I was to register my thumbprint I was asked if I was referred and I didn’t understand that aspect I used self sponsorship because I work I stayed my salary
was asked where I was going to which I mentioned , who I was going to visit I mention my uncle who had already sent a invitation letter to them where I work I stated that too and who is sponsoring my trip I said my self and lastly how I was able to sponsor my self I said I saved up for it and I am thinking of applying again this time I want to stay it either my spouse or uncle will be sponsoring my trip or should still stick to self
