Hello friends,
My sister is finishing her +2 in Nepal and is in immigration process which may be approved withing 2 years( if she is lucky) or 4-5 years. Now I am in dilemma of whether to send her for B.SC or something similar or just wait till she immigrates. If she is approved, she may not be able to finish her degree in Nepal, and could be waste of money for me. If someone has run into similar scenarios, I would appreciate your suggestion.

Knowledge is never wasted. You can transfer credits to US university.

That's true. But what should she study? If she goes for nursing or engineering, it costs a lot of money. And assuming she won't be able to finish it, is the investment going to worth it. I am thinking if some general subjects like B.SC Science will be good?

Seriously??
Study what you are interested in. If you look for the fees, Nepali universities and colleges are way cheaper than the cheapest in US.

Okay, here's my honest response--
Dude, have you heard about Plan A and Plan B? If not, here it is. For a moment, forget about her immigration conundrum and also ask her to forget about it too. When she gets the visa, you think about it later. Just let her enroll into a 4-year program of her choice, be it nursing, computers, etc. Since you said there are two possibilities for her to come to the States-- within 2 years or 4-5 years. If she is enrolled in a 4-year program and gets the visa within that 2-year period that you're talking about, she migrates to the States and transfers her credits and resumes her education where she left off. If her immigration process takes her 4-5 years, still fine; she will have enough time to complete education (not just a general BSc or BBS, but a more specialized nursing, or engineering). That way she can have a sell-able degree when she comes to this country. How much sell-able will our Nepali degrees be here is another topic that we can discuss some other time. But at least, I feel it's better for her to study in a field of specialization and quality and also for you to put your money at the right place instead of trying to spend your time in a college in Nepal waiting for the immigration process.

And there goes my two cents.

I am not trying to be cheap. But I just finished my school here and have no savings. So, if she goes to nursing or engineering, I definitely have to cough some serious money. But just wondering if I spent all those money and she gets approved before she finishes her school, how is that going to work?

Bro, I know times over here are lot harder than they think back home. Tara ke garney, garnai parchha ni bro. Sounds like you have lot of responsibilities back home, including your sister's education expenses too. But, just like KKP mentioned earlier, education in Nepal is a lot cheaper than here. Kehi raamro bishaya nai padhaau, visa kahile laagchha laagchha, how do we know? Also, since you said she is just finishing her +2, this is the 'prime time' in a student's life as they can choose a field of study that will eventually shape a career. So, don't let her waste it. We have all seen what happens when we lose a couple of years due to wrong major or say just due to lack of opportunity; I'm not saying you can never recover from that, but it's lot better to have a continuation in the same field that you chose at the beginning.

I understand you're not trying to be cheap, but if you can afford, please take a wise decision and enroll her in a more-productive field of study at her undergraduate level.

Good luck!!

So, Let's say I enroll her in undergrad school in Nepal like Nursing or engineering as Bandaina Sambhidhan says. And she has to move here leaving her undergrad unfinished, will she be able to transfer whatever she has finished by then? I talked to some students and they say that uncompleted studies in undergrad won't get transfered, specially for Nursing and Engineering. For my part, I transferred some credit from my 3 years degree from TU and got the evaluation from WES. So, does anyone has any experience with trying to get some credit transferred from your unfinished undergrad degree in Nepal? Please, don't be offended if I ask a lot of questions. I just don't know how to deal with it. She won't be able to come here and go back to finish her degree as she needs to maintain 183 days residency requirement to maintain her PR. I can try travel documents but that's a huge risk as it may be seen as an intention to abandon her PR status. And USCIS is not obliged to let her back after leaving for more than 1 year.

What sort of immigration process are you talking about that might allow her to get to the US within 2 years?

My mom has Green Card and my sister is under 21, 18 1/2 to be exact. We already filed for her. Everything depends on her turning 21 before her case is approved. For this class, the average wait time is 2 years. If she is not lucky, she will be bumped to another category and wait time is around 4-5 years.

If I were you, I'd ask and let her choose her study whatever she wishes to study rather than blatantly copying the fad of joining "Nursing" course.

In any case, she's not gonna lose anything by joining a course or taking lessons in a field of her choice. Don't worry about cost of joining a degree. I mean, the priciest Nursing/Engineering degree is gonna cost you what? 10 grand for 4 years?

"Idle brain is the devil's workshop".

Thanks Sherlock. It's not me. It's her wishes to go for Nursing. Anyways, I will talk to her again.

That is for US Citizens. If the parents or at least one of the parent is citizen, then the child's age will be locked in at the application date. But there is a different set of rule for GC holders. In certain case, USCIS can choose to process the case faster. But in either case, the child has to move to US before 21.
