To add a dash of otherwise necessary dramaturgy, you should know that the Department of Homeland Security’s Office of Inspector General (DHS OIG) in its November 2016 report concluded that over the past three years, USCIS issued at least 19,000 green cards with incorrect information, or were issued as a duplicate. In most cases, this involved forms submitted through the online system.
Over the same three-year period, USCIS received over 200,000 notifications from approved applicants concerning missing green cards, partly as a result of cards being sent to wrong addresses.
Writing this, we prepared you a quick matrix, which shows the differences between filing official government forms by paper and online submission. It may help you to determine, which option you feel comfortable with.
Good news: Even if you filed your application by paper, you can still create your USCIS online account to receive updates.
For more convenience, we recommend having a USCIS account with the government official website. You can check the status not only when you replace your Green Card, but also for other official government proceedings, like those related to: U.S. Citizenship, Alien Registration Number, or other lawful permanent resident status processes.
