If you're younger than full retirement age, continuing to work, and will earn more than $16,920 next year, then Social Security will further reduce the amount you receive in Social Security income by $1 for every $2 dollars you earn above next year's income limit.
The narrowest distance between mainland Russia and mainland Alaska is approximately 55 miles. However in the body of water between Alaska and Russia, known as the Bering Strait, there lies two small islands known as Big Diomede and Little Diomede.
So any part of the Bering Sea that is further than that from both countries, is considered international waters. But between mainland Russia and Big Diomede Island is only 19.2 nautical miles, and between USA and Little Diomede Island is only 19.5 nautical miles. So trying to go up the Bering Strait (not Bearing Straight) from the Pacific into the Arctic ocean, you would have to enter either Russia or the US.
