I and my spouse have been granted green card recently. I am 80 years of age and my wife is of 75 years of age. We have deposit accounts in foreign country where we worked earlier. My spouse is a state government pensioner. The value of our deposits are more than $100,000. Our income in foreign country is mostly interest income plus pension of my spouse. We have been regularly filing income tax returns in the foreign country separately on individual basis. We have no income in the US. For the current year 2013, we had resided in the foreign country till July 20. I wish to know the following for 2013 tax year in US:
1. Whether the interest and pension received abroad is taxable in US?
2. Is it sufficient if we declare the value of deposits to the treasury.
