Hi to all, I'm Sam

[Terpe]

Hello Terpe, I have question regarding my passport because last year of june we go to consultancy agency here to process our documents for applying tourist visa and I got my visit visa within 2 weeks and we purchase my ticket and I put 6 months Uk but the consultancy agent said that 6 months ok. so when I arrived to heathrow the immigration question about my ticket why 6 months because your only a tourist visa and they have interrogation about my ticket and after that they decided to refuse my visa they put REFUSAL OF ENTRY.

I'm not sure I understand any of this.
The tourist visa is issued for a validity of 6 months as standard.
When you submitted your visit visa application what was the visit duration you requested?
It's not usual to be refused entry at the border as the holder of a valid visa unless they suspected that you had insufficient funds available to you, or that you were not a genuine tourist with adequate tourism intentions but making the visit for undeclared purposes.
In any case it has no impact or bearing on your application for Spouse/Partner visa for settlement.

...and after that one of my friend tell me to change my passport from married to single so i have a passport using my single family...my question is there will be conflict when I planning to marry because I know one of the requirements is your passport...pls help me thank you

Don't understand this either.
I thought you planned to get married in July 2013?
How can you have a passport in married name ? Unless you were previously married and still using that name?
If you were previously married do you have full annulment documentation

The requirement for your passport is for ID checking and for entering the approved visa.
Your passport and the marriage certificate will provide the evidence needed.
Many folks here in UK still have passports in their maiden name despite getting married, applying for a visa, travelling to UK and securing employment here.
