Hijaab and Niqaab

Q: In Indian airports, we are required to show our faces for immigration. There is no segregation for women, and many people are around while I reveal my face. What should I do?

Q: I just applied for a part-time job and they require that I remove my pardah (niqaab). I usually do not wear it in my home town due to my home situation as a revert and my family is against it and out of respect for them I do not wear it. However I made the intention to wear it full time even though my family would still disagree. 

My question is: What is the ruling on this and would it be advisable to wear it even though it may cause arguing and tension at home, and should I ever take off my niqaab (in future) for the sake of a job?

Q: When I go outside to my back garden to throw something in the trashbin or do quick task, sometimes I don’t wear a headscarf or I wear it loosely. It can be inconvenient to have to put on proper hijab if I’m only going to go out for a few seconds. However, I usually peek out to see if the neighbours opposite our house have their lights on in their window and/or if they are actually looking out of the window at the time of me going to the garden. If I can see them then I will cover myself, otherwise I won’t. If a couple of strands of hair are visible then I don’t see it as an issue as they would not be able to see my hair all the way from their window. Is what I’m doing permissible?

Q: My brothers wife says she has an inclination to females which she often has to fight... A couple of times she got caught in shaitaans trap. How should purdah be observed in front of her? Should my face be covered as well?

Q: I am a female and I wear abaya and scarf but not the niqaab (face veil). I am trying my best to cover my body properly and have heard that the face veil is waajib, however, my question is, do I get sin if I do not wear the niqaab? I do however wear the appropriate attire besides covering my face.
