Hi there, I am a US Citizen. I have a fiance who is out of status
since 10 yrs ago.  We have been together for about 4 years, and we
have 2 years old boy.  I'm going to marry her next month, and will
petition for her. My questions are :
1. Should we use the lawyer service in order to sponsor her? because
we would like to save some money since we have to file lots of forms.
2. Will the USCIS deport her and make her go back to her country first
before they granted her a greencard?
All comments and answers really appreciated.

Hi Cooz,
There are Researchers with great records for answering immigration
questions, but they may be more likely to take the trouble if you
increase the price, there is quite a bit of work involved.  You might
check the FAQs on pricing.
You can do that by accessing "my questions" and amending the price.

The USICS site recommends avoiding lawyers.  You can find it yourself,
but I expect that a Researcher experienced with the subject can find
and interpret the pertinent information a lot better  - for a price.

Good luck.

Your 2 year old boy would make deportation pretty tricky for the UCIS

Since she has 'flown below the radar' for 10 years, maybe you would
have an easier life keeping it that way.

Generally I've found that getting a book on a subject is very helpful.

I've also found that lawyers are expensive, especially when they are
just doing paper pushing.  The same goes for accountants.
