How to get DECC document?

We would like to inform you that if your query regarding the permanent residence of the parents is in the form of a green card that carries many advantages, such as, the most important, the ability to reside and work legally in any of the 50 states. Other perks of holding a green card document include the following:
Ability to travel freely to and from the United States
 The possibility of sponsoring other family members to obtain a green card on your own, and to be eligible for federal education grants and other benefits,
 Eligible to apply for US citizenship after a five-year period.
 There are some downsides as well, for example, lack of protection from deportation to your country (for committing a crime), not being able to vote in US elections, not obtaining citizenship for your children if they were born outside the US, or simply the time and effort required to complete the green card application process. However, we still believe that the pros of carrying a green card outweigh the cons.
