hi to all,
i have been reading all about visa and the permit as i`m moving to swiss on saturday, my wife applied VISA for me based on family Reunification and i had i called this morning that my VISA is approved.
my questions are :
1.Do i need to buy RETURN TICKET or ONE WAY?
2.My wife was telling me i have only three months VISA, i was telling her yea,but i have to go migration to register and get 5yrs like her , she said NO. so i want to know who is right . ME or MY WIFE?
MY wife is in luzern, that is where my visa was approved.
she is EU with B permit for 5yrs.

You will go and get a permit like your wife did for 5 years. It doesn't matter if you have a return or a single because the visa has been granted.

If your wife is EU then you will have the right to work as well.

I'm confused. What kind of visa did you apply for and what has been approved? Are you and your wife on the same page about what has been applied for?

If you applied for a family reunion residence permit (which as a spouse of an EU citizen you're entitled to do) and it has been approved, it will be the same permit as your wife's permit. Nothing more to be done - all you need to do on arrival is contact the gemeindehaus (local town hall) and collect it. I assume you made the application at the Swiss Embassy? Once the Embassy has been notified that your residence permit has been approved in Switzerland they will contact you and ask you to send them your passport in which they will stamp a visa for entry into Switzerland. When you arrive you should register at the Town Hall within a week of your arrival.

A short term (three month) Shengen visitor's visa to visit family in Switzerland is something else entirely.

we applied for a family reunion residence permiti in swiss. but i think i have 3months entry which is schengen visa, the embassy told me.
NO swiss embassy in cyprus. non EU but based in cyprus and my wife from Germany with B permit 5yrs.

It sounds very odd that you would apply for a family reunion B permit and end up with a three month Schengen Visa. I don't think the process work like that.
Also, EU citizens are entitled to family reunion, regardless of the nationality of their family members, so there should be no problem getting one for you, provided that is what you actually applied for.

If family members of EU citizens don't have EU nationality, they may be subject to visa requirements when entering Switzerland before having recieved their family reunion permit. This might be what you are talking about. In other words, your B permit may be waiting for collection in Switzerland and the 3 month visa allows you entry into Switzerland to pick it up.

If you're having problems communicating with the embassy I suggest your wife goes to her Gemeindehaus in person to sort this out. She should ask them if your B permit has been approved, and if not, why not.

I'm pretty sure that's what he said/meant in the first post.

YEA THIS IS MY SITUATION @ THE MOMENT. I NEED A VISA TO ENTER INTO SWISS.

So what is your question?

Let me see if this helps
1. You normally dont need a return ticket, but the immigration in your country of departure would probably create a problem with a single journey ticket.

Part of the reason for this is the answer to your second question.

2. You are given a normal visit visa (Schengen) and this is valid for 3 months. You should enter switzerland with this visa and then get your B permit issued. You are not a B permit holder until the commune issues you with the permit. Your permit is just approved not issued. So both you and your wife are right.
