The Green Card is literally the cherry on the cake for all immigrants, since it is the permanent authorization to live and work in the USA. In general, the green card is valid for your whole life, but after ten years or if you are losing the green card, you have to deal with the so-called I-90 form.
You have to apply for a new green card, if your current one is almost 10 years old or if you have lost yours. This is a completely common process in order to extend the validity of your green card. You would have to deal with the same bureaucracy, if you want to renew your national identification card of your previous home country. Now the USCIS (U.S. Citizenship and Immigration Services) deals with your inquiry.
The green card is the most important document for all legal permanent residents in the USA, that is why you should bear in mind when it has been issued. The application to renew the old one or in the case of its loss is being send to the USCIS with the form 1-90 (Application to Replace Permanent Resident Card). Take enough time for the process, since it can take up to 12 months until you actually receive the new card.
The USCIS has introduced an even easier way to fill out the application with the help of a mobile-responsive procedure. If you have a smartphone or tablet, then you can use the advantages of the mobile friendly technology for this paperwork. Your documents (e.g. passport) can be uploaded with the help of your smartphone camera, since you can access your files. The online form guides you through all case-related questions, gives you instructions and makes the process of renewing your green card very self-explanatory.
In order to use this handy service, you have to create a free online account on the USCIS website. In the end, the application via mail is exactly the same than the online version, but you do have a couple of advantages using the electronic application:
Lawful permanent residents, who file the renewal of the green card with an immigration attorney, cannot use the online process for smartphones. Due to technical reasons, they have to stick to the regular online application or by sending it via mail.
