Should i live the US before turning 18 for green card

I was requested by my dad in 2005 and my cases is already moving. I came here illegally in 2004 ... i have talked to some lawyers and they say that i should live the country before i turn 18 because then i will be punished because i turned 18 here in the country. im 17 and turning 18 July 1st... do you guys recommend me staying or leaving? they also said that if it takes longer than to get the appointment for interview and i go over 18 1/2 i might be punished.

If I were you I would leave so that you dont get that 10 year ban

Do you know when your case will get approved ?

What "they" are saying is accurate.The "punishment" is a 3 year bar,and if you stay six months longer it becomes 10 years !

You choices are simple:

1.Visit home and receive green card and come back legally as a Permanent resident without issue

2.or stay in the US illegally past 18 1/2,give up your green card process and wait until Dream act possibly passing whenever in the future.

What do you mean by approved? By what i know from lawyers is that the case is moving.
I received the $70 letters that i paid already

So i've been told to leave as soon as possible cause my bday is july 1st

So do you guys recommend me leaving back to Mexico and wait for interview? and i won't be punished....
Also how can i prove that i left before july 1st if i am playing from Tijuana ?

***flying

Also come lawyer told my mom to cancel her petition since my dad is petitioning us because if not they are going to give her a band but would that work?

I'd leave! (As long as I were guaranteed to be able to make it back).. I would've taken that option if I would've know about it at 18!! ....now I'm 22, my mom is a few months from citizenship and I'm still at square one.. Look at it as a vacation.

Yes i think that is what i am going to do

If this person leaves, I thought the 10 year ban applies still.
