Repeating the sajdah tilaawah aayah in a musjid or classroom

Q:

1) If I am reading a sajdah tilaawah aayah repeatedly on the same spot, then only one sajdah is compulsory. However, if I am in a musjid and I am reading the same aayah while moving around, then how many sajdahs do I have to make? Does the distance I cover while moving around make a difference?

2) If I am reading the same sajdah aayah in madrasah in the same classroom but at different spots, then how many sajdahs do I have to make?

Marrying a Catholic girl

Illegitimate child concealing his right identity

Q: A child was born out of wedlock but he still uses his actual father's name everywhere to avoid embarrassment. He does that because only a few people know he is an illegitimate child. If he uses his mother's name this will lead to the suspicion of people and even those people who don't know that he is illegitimate will come to know about it. It wasn't the child's fault to go through this embarrassment. Is this fine and if not how should one go about to avoid people's taunts?

Working while on a visit visa

Q: It has been 4 months since I came to Saudi Arabia on a visit visa. There is a man known to my father who has a business. He gave me a job in his business because he knew my father. Now the main thing is, is it halal for me to get this job on a visit visa? Because, I did not come here for work. And I'm working under the guise of the Saudi government. So is it halal for me to work? Or is it forbidden?
