She needs to go back to Mexico and stop abusing and breaking our systems and laws.
If your friend's BF has a Permanent Resident card he is NOT an illegal alien. Geez, do you think everyone from Mexico is illegal? Her marrying him will not make him a US citizen but it will help him get a green card and that is the first step toward applying for US citizenship.
The rest of your question makes no sense. If she's knocked up she should marry him right now. Don't know how his medical issues affect this question.
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.
