Yes, it's five months for U.S. citizen filing for a spouse, parent, or child under 21 petitions, but those classifications are not subject to numerical limitations. Visas for unmarried sons and/or daughters over 21 are not the same thing. As of December 31, 2009, the California Service Center was adjudicating U.S. citizen filing for an unmarried son or daughter over 21 petitions submitted on June 02, 2005.
Looks like they have not reached any I-130 in your category from 2006 yet. If your father filed the I-130 in 2006, and it is taking them 4.5 years to make a decision on the petition in your category, your father should hear something in 2010 of 2011. The State Dept.
Is issuing visas in your category to beneficiaries of petitions filed on June 22, 2004, a waiting period 5.5 years.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
