What was your company was thinking?! That area is very heavily gang infested and it is not a safe place to live.
I am a 47 yr old native Houstonion, and I grew up 4 blocks from Sunnyside Street. My family lived in the area for a long time and finally when things got so bad, my parents had a house built out in the country and moved away in the early 1990's.
In 1992-1994, when my son wasnt yet school age, I rented a house in the area because I was going through a divorce and I couldnt afford anything in a better neighborhood... and when my son was about 4 years old, while we were at the park, two thugs held a gun to our heads in an attempt to steal the car we were in!
Both grandmothers lived in the area too, until they could no longer live alone. From where my childhood home was located, one grandmother lived 1 street to the north and the other grandmother lived 2 streets to the south. Then when my maternal grandmother had to go into an assisted living facility in 2001, I moved into her house and was there until 2005 when she passed away... so I actually lived in the neighborhood as recently as 4 years ago.
I dont know if you have children, but you will not want to send them to any of the schools in that area. In 2001 my son was about 10 or 11, and there was no way I was going to allow him to go to the schools in that area... so I sent him to a private school for 6th and 7th grade, he was homeschooled for 8th grade, but when he was ready for high school, he went to live with my parents to avoid having to go to the school in that neighborhood.
I actually worked in the elementary schools in the early 80's and then again in the early 90's... and there were no fewer than 12 distinct gangs in the elementary school I worked with!
Break ins and vehicle thefts are a very common occurrance as well... you will want to avoid going out of your house after dark too... and unless you are able to sleep through the sounds of gun shots due to drive by shootings (which I actually learned to do - except for July 4th and New Years Eve when for about 4 hours, it sounded like a war zone... my son and I would actually sleep in the hallway of the house to avoid being near any windows just in case a stray bullet came our way!) you might want to consider moving to another area of town.
Houston can be a wonderful place to live... and I love it, but sadly, there is no way that I'd advise anyone to live in the neighborhood that I grew up in.
Wishing you all the best with your move to the US and to Houston.
