Refused entry before, problem now?

[Spectre]

My girlfriend tried to come over to the UK from the US nearly a year ago now for 6 months but on entry she got sent back from immigration saying that she and I didnt have enough money. Now she wants to come over for a couple of weeks over christmas then go back to the US, but will there be a problem with her having been refused entry before? If it makes any difference she has recently changed last name (divorce), I dont know if that would change anything or not, any help very much appreciated.

Perhaps she should apply for visitor entry clearance endorsement in the USA, prior to travelling.

Where a passenger seeking entry in this capacity holds a valid UK entry clearance refusal may only be considered under Paragraphs 321A and 321 depending on whether the entry clearance has effect of leave to enter or not respectively. See the ‘Cancellation of Entry Clearance’ section 321Ahere or 321 here for further guidance.

If the refusal was purely for lack of funds she would have a good chance of an EC being granted if her (and your) financial circumstances have now improved. The change of name is irrelevant for the purposes of the application for leave to enter.
