What are the Next Steps, after Getting a Green Card

Hello Dear members.

What are the next steps after Getting a Green Card ?

(First of all, I tried searching the forums for a reply to my questions. But was unable to find any thread in this regard. So i created a new one)

I had applied for a Danish Green Card and, it has been approved. Now i have a few questions, and would warmly appreciate if you could help me with the answers.

1. What is the next step, when I land in Denmark.I was reading regarding registration with the CPR/Civil Authorities ? How much time does that take. Do i need to do anything else apart from that ? Tax card, how do i apply for it ?

2. Where can i find cheap and decent accommodation for 10 - 15 days, whilst i do the CPR registration and search for a job ?

3. I am an Graduate Engineer + MBA working with a Software company in my present location (India/US). Are there any particular regions in Denmark that have more of IT/Software companies .. (e.g Bay Area in US has more software comapnies than the rest of US)..

4. What is the average in HAND (after Tax)Salary one should be getting for a decent lifestyle (not extravagant.). I Do understand that Dane's have working partners and that helps support household. But if i was the only person earning, what should be my expectation.

Thanks in advance. I know the questions are long and some may be redundant. I apologize. I look forward for your esteemed guidance.

Cheers !
