I have already written a letter, and I think I am going to make a timeline as well. I think it would make it a little easier for the immigration lawyer to not only read the letter that I am submitting, my husband is submitting, our families and friends but also a timeline. If they need to know the answer to something quickly, or check a date they can just glance as a timeline. Not sure if it’s a good idea or not, but it can’t hurt!
