I've read a lot of threds on the topic "
Mutterschaft/Elterngeld/Arbeitslosgeld", but couldn't find a suitable
solution for our issue as my wife's case is a mixture of all of them.

First of all our employment/residence history in Germany:
I came to November 2007 on § 18 AufenthG, and my wife joined me on
dependent visa § 30 AufenthG in February 2008.
She is working Teilzeit since December 2008 and her job contract ends in
June 2010.
She is expecting baby in July 2010.

So far I came know that she can't avail Elterngeld as she has neither
completed 3 years of residence nor worked for 2 continuous years in
Germany.
Please correct me if I am wrong.

Now my questions are :
1. Can she avail Arbeitslosengeld DURING her Mutterschaft (that is 6 weeks
before and 8 weeks after the delivery )?
2. Can she avail Arbeitslosengeld AFTER her Mutterschaft ?
2.1 If Yes, can she choose to remain at home for 6 months after delivery
(Mutterschaftsurlaub) and avail Arbeitslosengeld during this period ?
2.2 In case if she is NOT eligible for Mutterschaftsurlaub, can she go on
holidays for 2 or 3 months while availing Arbeitslosengeld ?
3. Can she avail Elterngeld once she becomes eligible after 3 years of
residence ?

Our future plans for holidays and our parents visit to Germany all hang on these questions.
Hence requesting for your expert opinions/answers.

Hi there, the maternity holidays starts 6 weeks before the delivery date. If your wifes contract ending during this period , I understand that arbeitsamt will pay you the maternity benefit.
I dont know about the arbeitlosengeld , but u should try for elterngeld etc.. Check with the office they will check and inform you about the eligibility.
Best wishes...

So far I came know that she can't avail Elterngeld as she has neither

I dont think there is restriction of 2 or 3 years for elterngeld eligibility.

You are mixing Mutterschaftsurlaub and elternzeit.
Mutterschaftsurlaub is 6 weeks before and 8 weeks after birth. After that period it is called elternzeit.
Mutterschaftgeld is paid by health insurance (13 euros per day) and rest is paid by company.

Elterngeld is calulated based on previuos earnings (does not matter fulltime or parttime). It is 67% of avg of 12 months before Mutterschaftsgeld.

Hope this helps.

Friends, thanks for the inputs !!
@babashankar: Thanks for correcting me.
"Elterngeld is calulated based on previuos earnings (does not matter fulltime or parttime). It is 67% of avg of 12 months before Mutterschaftsgeld."
Does it mean that Ausländer is eligible for Elterngeld, if he/she has worked in Germany for the last 12months before child birth.
Here I found the rule :

Is my understanding right ?

If you can understand german check this forum

I am not sure of limited work contracts. But for unlimited work contracts (even if have worked 3-4 months before baby birth) you will get elterngeld.

It doesn't have to be 12 months. It could be 3 months but the average salary is calculated on the basis of the last 12 months.

There's no restriction on limited work contracts,

Check the law to see if your wife is eligible,
