This sounds like something she might want to ask her consulate about. It could be very serious if she is discovered living illegally. Her consulate can offer guidance on how to make her situation work.

The easy expat guide to Amsterdam also offers information on living in the Netherlands in general, and has an informative section on visas (http://www.easyexpat.com/en/amsterdam/d ... t-visa.htm).

"Once you have entered the Netherlands on a tourist visa it is NOT possible to change your status as a tourist and to obtain a Residence Permit. All international guests must report to a police station (the Aliens Department) within 8 days of arrival in the Netherlands"

It sounds like she might need a "D-Visa: Permission for temporary stay longer than 3 months, MVV
The MVV ( Machtiging tot Voorlopig Verblijf) is a visa/permit for a period of 3 months to a maximum of 1 year, after which it can be renewed without leaving the country. You need to have an MVV if you want to apply for a residency or work permit. You could need to take an Immigration and Citizenship Exam (Inburgeringscursus) at the Dutch embassy in your home country before you leave for the Netherlands."

Hope that helps!

 

thanks for the information every one..
