If I become a citizen within the United States can I bring my younger brother?

I am going to take the U.S Citizenship Test and If I pass I was thinking just about bringing my younger brother who is from Bangladesh. Can I bring him If I apply for him?
Answers:   
you can file for him to become a resident, but it can take many years depending on his age.
However, you can not bring him here to live until the application is approved or he comes on some other immigrant visa within the mean time...
You can apply for an I-130 for your brother as long as you are over 21. However, note that siblings are 4th preference. Currently, 1st nouns (adult unmarried children of US citizens) are at approximately 6 yrs. I know that the sibling preference for the Philippines is at 25 yrs.
There has been greatly of talk about removing the 4th preference category altogether so if you intend to back him immigrate, you should get his I-130 ASAP. His place in line will renovate with your immigration status as well. you can file a petition for him but it will bring about 9-11 years for him to come with an immigrant visa

Razor, brothers and sisters are 4th preference and at hand are currently visa avaliable for petitions filed before aug 22, 1997, is that a miinimal period of time? and greeen card holders cannot petition siblings
If you are over 21, a citizen and competent to prove you can support your brother, you can sponsor him and the wait time is minimal.
If a green card holder applies for the same thing it take much longer. usually your parents will have to sponsor your brother if he is still a dependent child. if he is an adult, then largely he would need to apply for himself.
