The best way to say it in English is "I would like to decide my future career based on the outcome of my study abroad trip." This way you are providing a cause and effect of what your decision will be based on. An example of this is saying: I will bring my umbrella today, based on what the weather will be later.
“I would like to decide my future career based on the outcome of my study abroad trip.”
(留学で得られるものに基づいて、私の将来のキャリアを決めていきたいと思います。)
が一番の良い英語のフレーズだと思います。
こう言うことによって、自分自身の決心が何に基づいているのか、
原因と結果（cause and effect）を表すことになります。
他の、原因と結果（cause and effect）を表す例として、
“I will bring my umbrella today, based on what the weather will be later.”
(私は、このあとの天気がどうなるかに基づいて、今日傘を持っていきます。)
Studying abroad will help me decide what I want to do with my future.
Studying abroad will give me a chance to think about my future.
"Studying abroad will help me decide what I want to do with my future." This explains to the person that you don't know what you want to do yet but you will have a chance to decide while you are studying.
"Studying abroad will give me a chance to think about my future." This is another way of explaining that you have time to think about what you want to do because you are still going to study abroad.
"Studying abroad will help me decide what I want to do with my future."
（留学をすることで将来何をしたいのか、決めやすくなると思います）
これは、まだ何をやりたいのか決まっていないけれど、留学をしている間にやりたいことを見つけられる可能性があることを意味します。
"Studying abroad will give me a chance to think about my future."
（留学をすることで将来について考える機会ができる）
これも留学期間に将来何がやりたいのか考えることができる、という事を意味します。
When i go study abroad will use that as an opportunity to think of my future prospects
When i go study abroad will use that as an opportunity to think of my career
* When i go study abroad will use that as an opportunity to think of my future prospects. An opportunity is a chance.
Example Sentences:
Next week's trade fair is an opportunity to market your products.
Last chance to register for nursing.
“When I go study abroad, I will use that as an opportunity to think of my future prospects.”
（私は留学に行くとき、それを将来の可能性を考える機会とします。）
“an opportunity”とはチャンス、機会という意味です。
例文
“Next week’s trade fair is an opportunity to market your products.”
(来週の貿易フェアはあなたの製品を市場に出す機会です。)
“Last chance to register for nursing.”
(看護に登録する最後の機会)
I will make plans for my future after I study abroad.
"I will decide on my future after I study abroad."
Decide - to come to a decision after taking time to consider all the options.
Here you are saying you will make a decision about your future, after, not before, you study abroad.
"I will make plans for my future after I study abroad."
Plans - a list of things you want to do, to accomplish. You will make this list after your studies abroad.
Either way to say it, you are letting your listener know that you will not make a decision right away, but after your study.
“I will decide on my future after I study abroad.”
(留学を終えたあと、将来について決めたいと思います。)
decide=全ての選択肢を考慮したあと決定に至ること。
ここでは、留学の前でなく、あとに自分の将来について決断をすると言っているので、この表現となります。
“I will make plans for my future after I study abroad.”
(留学のあと、私は自分の将来について計画したいと思います。)
plans= したいことやすべきことのリスト。
留学を終えたあとに、このリストを作るという表現です。
上記ふたつ、どちらの文も、すぐに決めるのではなく、
留学後に決める、ということを聞き手に伝える表現です。
I will use my time studying abroad to evaluate what I truly wish to do with my future.
Whilst I am studying abroad I intend to use the time to get a clear picture of what I want my future to be.
Both of the answers denote the use of one´s time abroad studying to be multi faceted. Both give the notion of simultaneous action and thought process during the same period of time. The first response uses the more certain "will" intention. The second is more descriptive prose.
