I have seen on this forum many n-400 applicants applying for citizenship as soon as they complete 4 years 9 months.
I would like to know are there any time specific benefits like - you have to be a US citizen for atleast 5 years and so on... to get ceratin citizenship related benefits
US citizenship is definately great to have but why are n-400 applicants are in such a haste, as long as they are getting citizenship?? Just curious to know as I have had a laid back attitude towards applying for citizenship. With Visas and GC it was a very different scenario where you have to make sure you're always in status, and accidentally not get into any police trouble.
Experts please suggest
With one exception, I am not aware of any particular benefits where you have to be a U.S. citizen for X number of years before you are eligible for that benefit. The only exception I am aware of is being a member of the U.S. Congress. As I remember, you have to be a U.S. citizen for at least 9 years before you are eligible to become a U.S. Senator and you have to be a U.S. citizen for at least 7 years to be a member of the U.S House of Representatives (there are also age and residency qualifications for both).
I think for most of us the reasons for filing N-400 as soon as you are eligible have to do with immediate rather than delayed benefits of being a U.S. citizen.
For example, for some of us (myself included) it is important to be able to vote in the U.S. elections.
Also, depending on which country you are from originally, visa-free travel is an important consideration. For example, I am originally from Russia and I have to travel to Europe quite a lot for work-related reasons. Even with a green card, I still needed to obtain entry visas first for most European countries, which was a huge hassle. With a U.S. passport I no longer have to worry about that, at least for short-term travel.
There are also some immigration benefits that are much more substantial if you are a U.S. citizen compared to if you are just an LPR. For example, if you get married to a foreigner and want to sponsor your spouse for a green card, if you are a U.S. citizen, your spouse would come under the unlimited category (immediate relatives of U.S. citizens), with no annual quotas and no waiting time for an immigrant visa number to become available. By contrast, GC applications by spouses of LPRs are subject to annual quotas and even after the I-130 is approved, you may still have to wait quite a long time (right now about 2.5 years) before the spouse can file I-485 or start consular processing for an immigrant visa.
There are some government jobs that actually require you to be a U.S. citizen in order to qualify for those jobs.
Finally, the LPR status is somewhat fragile and may fairly easily be lost or revoked if you travel too much or commit certain criminal offenses (not necessarily serious ones). By contrast, revoking U.S. citizenship is quite difficult, can only be done by a federal court and in general happens rather infrequently.
