First, Congress, or the Legislature, is the House and the Senate combined.
To answer your question, at the federal level, there are no limits. As long as the Member keeps getting elected and aren't removed due to ethics, they can remain in Congress. Each House Member is up for election every 2 years, and every Senator is up every 6 years.

Long term congressmen tend to take their reelection for granted and long term incumbents are fertile ground for corruption. I believe its healthy for new people to become members of Congress.

Congress does not have term limits, and may serve in their position until replaced by the voters.
Congress does not have time limits. Individual congressmen have time limits in the sense that their term of office runs out, but Congress itself can take as much time as it likes.

As of 2012, there are no term limits for Congress.
Voters can set practical term limits on a US Senator or Congressman by voting him or her out of office in the general election. There is no way to pass a law or state constitutional amendment that imposes legal limits on their terms, however, because the US Supreme Court found that unconstitutional in US Term Limits Inc., v. Thornton, (1995).
