There's so much information online about the whole process and you can ask anything here on the forums.
If you don't have a criminal background or a complicated case like an order of removal or some other weird thing like that, there is no reason why you can't apply yourself.
Look over the forms, fill in what you are certain about, then come on the forums and ask about the questions you don't know.
Remember, the applications are the I-821D, I-765 and I-765WS. The G-1145 is optional.
Filing fee is $465 which must be paid in money order or check to "U.S. Department of Homeland Security"
Look on the DACA site and see what evidence you can submit to prove you meet all of the guidelines.
