When married in Thailand and you go through the right channels for a spouse visa when she arrives in the UK the only thing she is not eligible for is benefits. Can work as she can get a N.I. number and register at your GP surgery and get NHS service. But saying that it's a long and frustrating journey jumping through the hoops and haveing the right criteria ie house job and most of all money to support her.
My immigration office have always asked for 3 months and on the day of applying statements,book updated and guaranteed letter off bank all on the same day I apply for extension
I'm on the marriage extention and once ya done the first one it's a piece of piss going through the paperwork plus the money for your bank doesn't have to be international transfer.you only have to show 3months statements and update your bank book on t day ya submitting the extention.all these who are sayin its harder than the retirement ex probably use agents anyway.believe me it's a walk in the park to get the marriage ex.
