Hi all,

I am currently in Germany on blue card. I got offer from rotterdam for one year contract , and later extension. My company filing my VISA. I asked about my wife visa, they told that I have to make application for my wife myself.

I want to to know as we both have bluecard of Germany ,she can come along with me in Netherlands ? Right. Then we can file her visa? Can anyone tell me their experience , how much it will take for this? I have seen we need marriage certificate , birth certificates and all. Do I need to attest everything?

Please need this information.Look forward for your support guys..
