I think you should work in the U.S. this summer instead of being financially dependent on your wife. A man has to search for financial avenues for his family in order to cope with their basic needs and wants. Anyway, it's just for the summer vacation. Two months of not being with your child and wife is not that long considering the income that you will get out of working in the United States. It's a good thing that you are prioritizing the financial stability of your family. Mahirap din yata maging "chemis" (hindi chemist). "Chemisis naka-asa." hehe.
caveat: baka walang makuhang trabaho dahil recession doon ngayon.
