If I rightly remember, it should be some kind of UK official box where authorities register your marriage. No formalities, no nothing. Only a UK paper stating that your marriage has been registered in this "box". I don't remember the name but it could be quite usefull for you because for UE road, as well as for most national roads, the marriage should have some legal recognition-aknowledgment from the country of the European spouse.
Documents to submit for EU family visa are very simple :
- Marriage certificate and passeport for your spouse.
- Passeport for yourself.
- You may also send a copy of the EU commission new guidelines for 2004/38 as of july 2009 (you will find it here both in French and English :
http://multinational.leforum.eu/t488-No ... 004-38.htm ).
You may also give copie of the contract of your new job in Latvia and a letter asking the French Embassy to issue a EU 3 months visa to Latvia for your wife in order to go there with you while you will start your new job.
If no answer from the consulate, don't forget that you can start procedure against them one month after the deposit of your file (as stated in the EU guidelines, for the French road, you have to wait two months).
The most important is to get an official receipt from them with the date they received your file. If they refuse to give you this receipt, send them the full file by registered letter and use the receipt of the letter as the proof.
The new CEMAC biometric passeport has a chip on it.
The French consulates in Cameroon (both Douala and Yaounde) are some of the worst in the worlds. Hundreds of french-foreign families blocked for artificial challenge of legal documents or challenge of genuineness of marriage or no allowance for the kids to go to France with their mother. Hundreds of dready files. Some of them 3, 4 or 5 years old.
