Thank you for your reply. As for your questions:

My husband is a Turkish citizen, he is a tourism guide. We are married for 10 years. We got married in 1996. In 1998 I had my second visa since I was married, I also had, before I got married, both living and temporary working permit in Antalya. The last visa of 1998 got expired in 2000. The bankrupcy was of my husbands brother, it affected us financial, not legal.
I have a normal Dutch passport.
When I say my kids (5 and 7) depend on me I mean I don't have any family or others here to leave them with for a long period. My husband is away from home for days sometimes because of his work. They were born here in Istanbul.
