There are undoubtedly plenty of Jewsish people that look white. Though chances are, if you talk to them for a bit, they'll find a way to let you know that they're Jewish. Jews are too conceited and self obsessed to conceal their Judaism for long, they're God's chosen people and want you to know it. Even if they don't directly inform you, they'll show themselves with a combination of anti-white beliefs and narcissism - traits you should avoid in people of any race.
