It would probably be better for you to marry in NY really.
As your partner is a fiance is an EEA national you will have as his wife a right to apply for an EEA family permit once you are married. The UKBA does not charge a fee for this.
You will need to complete form VAF5 - EEA Family Permit and submit this to your nearest UK embassy. There are some VAF guidance notes to help you complete it. YOu can download both forms from the UKBA website.
You will certainly need to include the following documents with your application, there may be others after you have read the guidance notes:-
- a copy of your EEA national passport (endorsed by your embassy in the country of application); and
- proof of their relationship to you (for example, their birth certificates or marriage certificate); and
- a letter from you declaring that you are traveling with them or that they are joining you in the UK.
Here is a link to the supporting documents page of the UKBA website:-
You will be able to work in the UK. Once you are in the UK you can apply to the UKBA for a residence card confirming your right to live with your husband in the UK. This means you would not have to obtain an EEA family permit each time you leave the UK and then travel back.
The UKBA aims to reach a determination on each application within 6 weeks of the date of submission, but frequently overrun. I would start preparing it now so that you can submit straightaway following marriage.
