in all fairness, Stuart has handed you your ass here again. It's like you came to a gunfight armed with toothpicks. I don't know how much more of an online ass kicking you can take without just hiding your head for awhile in humiliation. Take a breather, do some reading. Look for a personality while on your break.
Even better that you deleted your stupidity then. It's apparent that fear owns you and your life. Best stay inside and these pages mate. Or learn to back up your own comments
Absolutely ensure that the agent sees your LTR visa or they will stamp wrong date.
And don’t walk away from agent until you have verified accurate stamp. If should be 5 years from date of issue OR your passport expiry date. Whichever comes first
