I'm Iranian. Iranian rice is lower in arsenic and carcinogens to begin with and the Iranian methods of cooking rice cut arsenic content by around 40 (quick version, aka "kateh") to 70 percent (traditional version, aka parboiled method). Rinsing/straining rice before cooking has minimal affect on arsenic, btw, but can reduce it by like 30% if you really go to town on it, but you will also wreck the nutrient profile. Usually it only affects arsenic quantity by like 10% while costing you vitamins.
Also, some rice types have much lower arsenic to begin with. Basmati white rice typically carries like half the arsenic and cadmium compared to your average white rice. Sushi rice also typically has lower arsenic content. As does jasmine rice from Thailand.
On that note, the source is also important. Pakistani rice is most likely to have high arsenic quantities, iirc, but it can vary depending on which rice you're buying. Some brands are far more conscientious of their quality than others. Still, even Pakistani rice is fucking amazing (having roughly half the amount of arsenic) compared to most American rice, but rice from California has a much lower arsenic profile compared to rice from Texas, Louisiana, or Arkensas. This is because Californians didn't go ham on arsenical pesticides in the first place. Probably California's Insecticide Law of 1901 had some effect on cutting on down bullshit pesticides before they ever saw serious adoption. Honestly getting white rice grown in California is pretty safe.
Getting white basmati rice grown in California, India, or Pakistan is usually around the best for arsenic levels (California best, Pakistan worst). Or just getting Iranian rice (which is generally even better, except vs California white basmati), but that's usually not as easy to find. Also learning to cook rice with the traditional Iranian method will wipe out an enormous amount of arsenic in your rice.

It's not that straightforward. While organic arsenic has carbon bonds that neutralize most of its harm factor, that doesn't mean all the arsenic found in rice is organic arsenic. In fact, rice is particularly at risk of absorbing inorganic (meaning "not organic") arsenic from the soil.
