If interest income is less than $10 so that I don't get a 1099, do I need to report it?

Yes you must report all income $1 or more.

You still need to enter the interest even if you did not get a 1099.  Get the year to date amount online or from your bank statement.  Enter like if you got a 1099INT.  Just enter the bank name and put the amount in box 1.

All income should be reported.

If you are a U.S. citizen or resident alien, the rules for filing income, estate, and gift tax returns and paying estimated tax are generally the same whether you are in the United States or abroad. You are subject to tax on worldwide income from all sources and must report all taxable income and pay taxes according to the Internal Revenue Code.
