About the method of FBI background check

I would like to know if the FBI background check is just criminal, or if they also do a credit check.
Thanks

If you committed financial fraud they will investigate.

But they don't do regular good or bad credit checks as far as I know.

FBI does background check on you just here in the US or in another country?

Nowadays, the backgroundchecks are far more thoroughly than they used to be.

They do work togheter with other intelligence agencies all around the world.

Will it be a collaboration among FBI,CIA and Interpol? I am just appalled because I know someone who came from another country with arrest but was able to adjust his status in 1992. FBI won't be able to pick this up?

Like I said they work thogheter with lots of other intelligence agencies such as CIA and Interpol.

If he/she adjusted status in '92 and didn't find out he/she should be OK.

The just are far more stricter after 9/11.

What was the arrest for and did he/she get convicted and if so where? Us or other country?

He came from a third world country. He was not convicted though, just wrote a check with insufficient funds for $2,000.00.He's a prominent engineer in the west coast with lots of properties.

For permanent resident applicants, CIA conducts the check, for naturalization applicants it is FBI. I have not heard about Interpol being involved.

CIA will check your background if you are a terrorist and FBI will check if you have crimes committed in the US only.
