When you are ready to come to America using family immigration, you likely want the process to move forward as quickly as possible. The opportunities that await here are what calls many people to the area. If you are ready to embark on a life in the United States, there are some ways that you can improve your chance of getting the documentation you need.
If you aren't in the country and need to apply for a family-based visa, you should file more than one application if you have more than one family member who can sponsor you. This can increase your chance that one of the applications will be approved. If one happens to be denied or if the sponsor passes away, you will already have another petition in the works.
Another thing you can do is to learn about the immigration laws. Any violation of the laws can lead to a denial of your petition. Even if the violation is unintentional, it can still have dire consequences. For that reason, learning about the laws governing immigration can help to ensure you don't do anything that could hinder your immigration petition.
Finally, don't count on the process going quickly. You should anticipate delays when you file your petition. In some cases, applications can take 3 years to process. This means that you must plan well in advance of your travels to the United States. If you are already here, you should file for your green card renewal as soon as you can do so legally so that if there is a delay, you won't run into trouble.
