The sequence of events are not clear? Did the Register Office Contact the Home Office and what written evidence did both HO and Register Office give you? Depending on the written evidence you MAY have cause to complain, but be careful as to Marry on a Visitor Visa is generally not allowed. If it had been the intention to come to the UK to Marry then you should have applied for a Marriage Visa which allows entry to marry and then leave the Country. You could then apply for a Spouse Visa from your own Country.Allright thank you... but how can i have broken the rules if the home office as well as the registrar after investigate on me told me that there is no law which can prevent my marriage and everything is legal??
Was your grandmother born in the UK? If she was and you have a passport issued by a Commonwealth country, you can try and get an UK Ancestry visa -
In your desperation to remain in the UK, you cannot apply for a Visa whilst here on a Visitor Visa and will do your cause NO good to stay longer than the date shown. It is possible your sponsor gave specific information on the time you would spend in UK, when she submitted a letter of Invitation which accompanied the Visitor Visa application.
