大部分券商应该都可以吧 schwab是可以的至少
可以直接在政府网站 https://www.treasurydirect.gov/ 上面买,
These Treasury sales are technically auctioned off, not sold, and you won’t know the exact rate until it’s complete. We’ll usually have a good estimation in advance of the expected sale rate.
也可以找券商买such as Fidelity, Schwab, or Vanguard.
The major advantage of buying through a brokerage is that you can choose to hold until maturity or the bond can be resold at any time on the secondary market.

多谢!从税务角度,不管是政府网站买还是券商买bond都是不用交州税吗?
在fidelity上看到的解释
Tax advantages
Interest income from Treasury bonds is exempt from state and local income taxes, but is subject to federal income taxes. Other components of your return, however, may be taxable when the bonds are sold or mature. If you buy a bond for less than face value on the secondary market (known as a market discount) and you either hold it until maturity or sell it at a profit, that gain will be subject to federal and state taxes. Buying a bond at market discount is different than buying a bond at Original Issue Discount (OID). When a bond is sold or matures, gains resulting from purchasing a bond at market discount are treated as capital gains while OID gains are treated as a type of income.
