i am of singapore national and i am allowed to enter UK on visit purpose without applying for a visa and stay up to 6 months.
during last entry to uk, upon arrival at immigration, was asked by an immigration officer how long i am staying, told him about 6 weeks. He confirmed my entry by reiterating that i will have to leave by 6 weeks but the passport stamp indicated ''leave to enter for/until 6 months'' with a circle on the word ''for'' and a special code reference which i believe traces to a record he saved on file about the details i had given.
into the 4th week of stay, my boyfriend proposed to me. we are already getting along really well and feeling the bond and relationship progressed deeply. i had also previously visited him in uk before this last visit. i decide in order to make a right decision, i will stay a lil longer to be more sure that we can live together as a couple.
i tried to contact several bodies to enquire if i am allowed to stay more than the 6 weeks i reported to the immigration officer. One immigration officer with no name advised but only a warden number given to me when i asked him for his name. He told me technically i am not breaking the law but might be a problem when i enter UK next time.. I further queried with ukba via email. i was advised by an officer from ukba that as long as i do not overstay the max date on my visa i do not need to extend. upon seeing that i felt great. In the end i stayed in UK for 4 months 2 weeks.
however right now as i am about to apply for the fiancee visa, i did a lot of homework and followed the instructions to a T, and i have more than sufficient funds to support myself as well as i have clean records etc,
but as i pulled that email out from the ukba officer , i realised in his reply he mentioned the word ''VISA''!!

i have a few questions below, i hope someone could kindly advise me, i thank all of you in advance.
1. is that considered overstaying? am i considered breaking immigration laws in any slight way? will i face some kind of detention at immigration upon arrival even if my fiancee visa application eventually is approved and i am issued with an entry clearance into UK?
2. during preparation of the supporting docs, i came upon 2 criterias for me to prove in order to apply for fiancee visa under this link http://www.ukba.homeoffice.gov.uk/visas ... documents/ :
•evidence that you intend to marry or register your civil partnership within a reasonable time (usually 6 months)
•evidence that you intend to live together permanently after you have married or registered your civil partnership
However the above 2 items of supporting documents from the UK border link is impossible for me to provide because it is not possible to prove before having an entry clearance in hand first before entering and applying to register marriage nor can i apply for any joint bank account to prove we intend to live permanently together. Does anyone know what am i supposed to use to prove as evidences for the 2 points above?
thanks everyone in advance
