Green Card Application
The green card application can be done by anyone at any time. This is because the government wants to afford equal opportunities for all people who wish to live and work in the United States. In fact you do need to go to an immigration lawyer or use any go between in order to fill out your green card application.
However, in order to fill out you green card application it is recommended that you do indeed fill out the application with an immigration layer, since it is important not to make any mistakes with the application form. Since, if you do make a mistake, then your application will not be accepted if there are any mistakes in it and then you will be forced to resubmit the application by the next year.
This then is the most important thing to remember when filling out you green card application. When you do fill it out, then remember to make sure that there are no mistakes in it. The authorities get many many applications a year, so they cannot afford time-wise to correct every green card application that come, so make sure to check ever aspect of the application before you send it to make sure that there are no mistakes.
