回复：请教退休计划问题。

1)请问 我太太能否买Traditional IRA?

The answer is yes, google spousal IRA.The contribution may or may not be tax deductible.

2)还有我本人和太太能否再买 Roth IRA？

The answer is yes, but if your income is beyond the Roth contribution limit, you can not directly contribute to Roth, you need to contribute to traditional IRA first, then convert to Roth. The pre-existing traditional IRA accounts may complicate the conversion process.
