Croeso i’r ffrwm, Megan! (Welcome to the forum). Like AnnaC, I’m an American, also. At some point, if you’re not there already, you will want to speak Welsh with someone besides the family pet. 
It’s at this point, you’ll walk out your front door, scan the neighborhood and realize you are the only Siaradwr Cymraeg in eyesight. It’s around this moment you check the costs of round-trip flights to Wales ($400-$1,000 and up) and begin to bargain with your brain how to justify this cost with friends and family just so you can speak to someone in Cymraeg. 
Now you ask yourself, “Why Welsh? I can find a Spanish speaker easier. Even Italian or Urdu are languages I can find someone to speak with.” Welcome to being a Welsh speaker in the United States. It’s a unique type of frustration. I personally blame @aran for creating this problem in my life. 
Fortunately, you live in Virginia and there are options for you:
Welsh Society of Fredericksburg
Robert Roser
1203 Harbour Drive
Stafford, VA

www.welshfred.com - good group from what I’ve heard.
The first Saturday of each month there is a meet up in Washington DC from 110:30-noon at Teaism Penn Quarter. Full details in first post of this thread. I’ve not been to it, but it’s quite the gathering!
Lastly, I run a meet up for East Coast speaker on Thursdays from 7-8PM.. Details on the link but it’s a group of SSiW members from Maine to Florida who range from beginners to intermediates. I present a topic of interest and each person tells a story then each listener asks the story teller a question. After a couple of sentences, the speaker translates into English. This way we all learn. It’s a lot of fun and you are welcome to attend.
