I applied to go on a 2 week vacation from work last month to the UK, But I was denied a visa. Note that I schooled in the UK (Masters) from 2015-2016, and was back in the UK in 2017 twice on seperate visit visas (sponsored by my dad). The last time in 2017, I had a six month visa, and applied to spend 2 weeks, instead I spent 107 days, by choice. This was a joint decision between parents and I as I was to resume for my phd in 4 months, so i needed to house-hunt and do some research and keep myself busy.. Note that I was not working or accessing public funds, rather my Dad had money sent to me each month( I have bank statements to prove).. my visa was application was refused last month, citing paragraphs v.2a and e. One of the reasons they gave was that the money in my accnt wasnt from my Dad’s account. They also brought up my last visit and hw I stayed 107 days instead of 2 weeks like I applied to. Note that my accnt was well furnished as my dad (my sponsor) directed a business payment into my accnt (More than sufficient).. i resume a Phd programme in october, I have already paid my fees, I only deffered it from march to october for personal reasons. more so, my Girlfriend (Ghanian) sent me an invite for her graduation for July. Do i stand a chance? How do i go about it? I am Nigerian by the way.
I can't identify the paragraphs you say you were refused under, but I suspect you actually mean Appendix V Para 4.2(a) and (e), which require you to establish that you will leave at the end of your visit, and that you have enough funds.
The ECO hasn't said it in so many words, but he believes you were working illegally during your 107 day visit. This is a serious problem for you to overcome if you're going to get a visitor visa any time soon.
If you are to apply again you will need to explain exactly what you were doing for 107 days and why, and provide supporting documentation if at all possible.
You will also need to document exactly where and how you obtained the funds for that trip, and for the trip you propose to make this year. You should include any and all bank statements that are pertinent.
It's not clear from your post whether the ECO is aware that you intend to return to study in October. Assuming that he is, you will need to come up with some convincing reason why you will return to Nigeria in July, only to return in October, a period not dissimilar in length to the 107 days.
You should be aware that a second refusal could adversely affect any future visa applications, including the study visa you will need in October. Consider whether your girlfriend's graduation is worth the possible risk to your studies.
