As an OFW, you have the privilege to earn in dollars and earn more than what you can earn here. Still, don’t be complacent. With the rising expenses back home and in the country where you work, it’s not surprising if your monthly salary is unable to cover all of your expenses (including shopping, perhaps). At this point, you might want to consider looking for an extra work for extra income.
Yes, it is possible. The good news is there are tons of business ideas available that allows you to earn additional money. This includes: 
1) Buy and Sell
You have two options here: you can try buying and selling goods from the Philippines to the country you are in or ship and sell items to from where you are to the Philippines.
The good thing about this business venture is that the possibilities are endless. The market for local products is big because Filipinos will always love the taste of “home.” It could range from native delicacies to toiletries or even food products. If you are on a vacation, fill your suitcase with local goods then sell it as soon as you’re abroad.
On the other hand, there is also a big market back home where Filipinos want to buy something from abroad that is not available here then send it back home. In short, you sideline as a shopper. Maximize the opportunity and put up your online store or Facebook page to make it easier for your potential customers to contact you.
2) Freelancer
Are you thinking of making use of your downtime? If you have time, consider working freelance like being a babysitter, chaffeur or driver, or an English tutor. If you can bake or cook, use those skills and offer your services at an affordable price. It will definitely give you additional income while working abroad.
3) Be a Blogger
Did you know that blogging can give you a lot of income opportunities? It will take time, but with the right tools and techniques, you can make money from blogging.
The key here is to choose a topic you are passionate about, say your life as an OFW. This will make it easier for you to write and reach your target audience. Just make sure to update it regularly.
4) Cellphone Loading Station
Believe it or not, more OFW prefer communicating with their loved ones through call and text. It is easier, faster, accessible, and more convenient than waiting for a decent Internet connection. At the same time, some services such as transferring funds or mobile entertainment requires load. Since there most Filipinos own a cellphone, take advantage of that by putting up your own loading station. It won’t make you a millionaire, but it will definitely help in giving you additional income.
5) Room Rental
Do you have extra space in your house or unit? You might want to try renting the space – or even a bedspace – to fellow OFWs who are in need of a decent place to stay. This could give you additional income, which you can use for equally important expenses or to help you set up your emergency fund.
These business ideas may not yield millions during the first six months, but it will definitely help you a lot in boosting your savings or giving you something extra in case something happened. Just be patient and committed and who knows, the income you will get from these “small businesses” could lead to something bigger, saying getting your own franchise of a food cart or even in real estate.
