My daughter is getting married,I want to take my TGF of 7 yrs with me have looked at some posts 

looks like a nightmare,( daughter marrying in FRANCE) then onto to Spain for aweek too stay with 

sister-in- law, then back to UK And then return too Thailand, how big a nightmare is it...........??

She would need a UK Visa and a Shengen Visa.

Not a nightmare at all, you just need to plan and evidence the applications properly.

 

As Light Beer says, she will need a UK  and a Schengen Visa, she should apply for her Schengen Visa at the Consulate with jurisdiction for the Schengen Country which her main destination, ie where she's spending longest time, if she spending an equal time in both countries then she should apply at the Consulate with jurisdiction for the country where she enters the Schengen Area.

 

There are pinned topics for UK and Schengen Visas at the top of the forum, they give a lot of detail about the requirements and procedures. 

Indeed, should be relatively simple if you prepare properly.

 

The posts on here and other forums about difficulties with Schengen visas are all about various Schengen embassies not applying the rules for qualifying family members of EEA nationals correctly.

 

A girlfriend is not a qualifying family member, so those rules wont apply to her.

Most of the topics were indeed on hassle with visas for eligable familymembers (spouse etc.) of non-EU persons married to EU/EEA nationals traveling to any other EU/EEA state. Some were also on regular applications concerning things such as an embassies wrongfully insisting or not informing about the right of direct access (by appointment, given within 2 weeks of the request) to the embassy or other sillyness.  But in most cases reading the instructions of the embassy lus the sticky topics here should be all you need to prepare properly and to be aware of your rights and answering the most common questions related to these visas.  But if you got any specific question, let us know. :)

Thank you kindly for your replies much obliged ,hope it is all as straight forward

as suggested, thank you again folks..........
